So What Can I see From Here?
Usually, the limit to how far characters can see will be some obstruction, such as a building, a forest, or some hills. Mist and darkness also limit vision. Sometimes, however, the characters will be on flat plains on a clear day and the only limit to their vision will be their perception and the horizon. Once something goes below the horizon, it can’t be seen. But where is the horizon?
|Height in feet||Miles away|
This table has been simplified for gaming use. On an earth-sized planet, the horizon for a six-foot tall person standing at sea level or on flat plains will be about 3 miles. This means that they can see features that are at ground level for up to three miles (depending, of course, on the quality of their vision and the size of the object). Features that are higher than ground level can be seen further.
To determine how far away you can see something, just add together all of the heights. For example, if a 6 foot man is on a 4 foot horse standing on a 30 foot hill, how close would you have to be to a 60 foot tall tower to see it? First add all the heights together 6 + 4 + 30 + 60 = 100 feet. Look at the table under “height in feet” and find 100 feet. Then look across under “miles away” to find 13 miles. So the tower could be spotted if it was no farther away than 13 miles.
You could see a 14,000 foot mountain a little more than 100 miles away.
This is good for seeing features on a map, such as lakes, forests, mountains, towns, etc. but knowing how far you can see is often not what your Player Characters need to know. Just because you can see 3 miles doesn’t mean that you can see a monster on the horizon. For that we need another table.
Perception Distance Table
|Creature – Fine||6” or less||30 ft. or less||5 ft. or less|
|Creature – Diminutive||6” – 1 ft.||30 ft. – 60 ft.||5 ft. – 10 ft.|
|Creature – Tiny||1 ft. – 2 ft.||60 ft. – 120 ft.||10 ft. – 25 ft.|
|Creature – Small||2 ft. – 4 ft.||120 ft. – 240 ft.||25 ft. – 50ft.|
|Creature – Medium||4 ft. – 8 ft.||240 ft. – 480 ft.||50 ft. – 100 ft.|
|Creature – Large||8 ft. – 16 ft.||480 ft. – 960 ft.||100 ft. – 200 ft.|
|Creature – Huge||16 ft. – 32 ft.||960 ft. – 1,920 ft.||200 ft. – 400 ft.|
|Creature – Gargantuan||32 ft. – 64 ft.||1,920 ft. – 3,840 ft.||400 ft. – 800 ft.|
|Creature – Colossal||64 ft. or more||3,840 ft. or more||800 ft. or more|
In this table “perceive” means that you can see it and may notice it with a perception check. If you do notice it you will recognize the creature type if you have seen one before. If you don’t know what type of creature it is you will be able to tell the creature’s coloration, size, shape, number of limbs, wings, etc. If the creature is moving, you will also be able to tell which direction it is traveling and about how fast.
“Identify” means that you can see details and may recognize an individual that you have met before.
Here is a simple rule of thumb that is accurate enough for gaming use:
Distance away (in feet) that you can perceive an item is its size (in feet) times 60.
Distance away (in feet) that you can identify an item is its size (in feet) times 12.
Round fractions down to the nearest 5 ft.
The item’s size is its longest dimension (height or width).
One more thing.
You can perceive a burning candle 1 1/2 mile away.

The Alabaster Portal Key
How do you smoothly run a weekly game if there is a lot of turnover?
What if you have dedicated players, for the most part, but every week you don’t know how many will show up? Some may have to miss a session (or two or three). New players may show up and want to join the group. Existing players may need to drop out but may want to re-join the group in a few months.
I think that the best way to handle this will be to have every session end back at the tavern, or some other busy place, or back at their home base wherever that might be.
It solves most of the problems and creates some new ones. It solves any leveling-up in the midst of play problems, all leveling up will occur between sessions. It makes it easy to accommodate missing players, their PC simply doesn’t play but can play next session. It also makes adding new players easy, their character simply joins the group for the new session.
It also creates some problems. The first is how can you do that, especially when higher level characters may be traveling far and wide? Even low-level characters that are adventuring close to home may have a problem leaving the dungeon and coming back in any reasonable time frame. It also restricts somewhat which adventures you can run. For example, any “ticking-clock” adventure where the characters must finish in a set time frame would be hard to run. Also, you couldn’t stop an adventure in the middle of an encounter, which isn’t a big problem, but it does limit you somewhat.
Here is how I propose would do this. Give the PCs a magical artifact (maybe the tavern owner gives it to them or they save a strangers life and he gives it to them). At first level, they take this with them and when they activate it, they are all returned to the tavern. When activated again, it returns them to wherever they were before.
To introduce it into an existing campaign, the PCs could find it wherever they are adventuring. When activated it sends them to the tavern. The tavern owner can be a sympathetic NPC who lets them continue to use it.
Here is an example of how this might work:
The owner of the tavern escorted us down the stairs to a large dusty basement. He then called for the crowd to gather around. He held up a large white chess piece and declared “One of you lucky people will be allowed to purchase this tonight. It is a magical key.”
“Have you ever been a long way from home and wished you had a way to return home quickly? With this magical key you can instantly return here any time you like. Just take it with you wherever you roam and when you want to return simply hold this key in your hand and say the magic words. It will open a magical doorway between wherever you are and this archway.” He pointed to an ancient arched doorway in the wall behind him. It was completely sealed by the same stone that made up the rest of the walls of this old chamber. “But wait, there’s more! If you want to go back to where you were, simply approach this archway with the key and say the magic words. It will open the doorway at the same location you left. You could take a long trip and return home to your warm bead each night. ”
At that point most of the crowd turned around and returned to the drinks, snickering and shaking their heads as they climbed back up the stairs.
To the few of us that remained, he said “You appear to be adventurers. Just consider the possibilities! Imagine you are cleaning out a dungeon. You have fought many monsters, defeated deadly traps and collected ancient treasures, but at the end of the day there are still other dungeon levels remaining to explore. With this key you could return here, sell or lock up your treasure, identify any magical items you may have found, replace any lost or broken weapons and amination, rest and heal your bodies. Then when you are ready you can return refreshed and resupplied. You could even recruit other adventurers to help if you need to and they could return with you. And if one or more of your party needs to stay behind while you return to the dungeon, the ones who return only need the key and the activation word.”
I asked, “What if we are being chased by monsters? How quickly could we open the doorways?”
“Well …” He swallowed hard and said, “You know this was never intended to be used as an escape from battle.”
“The magic word is really more of a ritual. It takes 10 minutes to activate the portal.”
“And what if we are being pursued? Can anyone pass through? How long does it stay open?”
”Well, yes any creature could pass through once it is open and it normally stays open for one minute. However, you can close it at any time by tapping the key on the side of the passageway.”
I thought about this for a minute and then said, “Okay, say we are in a dungeon, a patrol is approaching so we hide around a corner and use this to return here, are you saying that we could just wait here for a few minutes and, watching through the doorway, go back when the danger had passed?”
“Actually, no. I may have neglected to mention that you must wait until the next day, at least 8 hours, before you can return. Also, the two portals are filled with a mist so you won’t be able to see what is beyond.”
I asked, “So if we go from here to a dungeon we will have to wait 8 hours before we can return?”
“No, not at all. When you leave here you can stay as long as you like or you can return immediately. Or, I mean, after the 10 minute activation ritual.
“It is just that when you return here you must wait until the next day to return to the dungeon. And, even if it is the next day, you cannot return unless it has also been at least 8 hours. So you can come back here a little before midnight and return 8 hours later. If you return here after midnight, you will have to wait until after midnight the following day.”
I then asked, “What if I am in the dungeon and just need to store something we found, or retrieve something that I forgot? You say that the portal stays open for one minute. Could I open it and then quickly come here to pick up something and return? Or if someone is wounded, I could open the portal, let them run through and then close it behind them. If I understand what you have been telling me, I should be able to do that as often as I wanted to. As long as I am not on this side when I open the portal, I can open it whenever I want.”
He answered, “Yes you can do those things, however there is another restriction I forgot to mention. Each time you use the key to activate the portal, the key must pass through to the other side and remain there when the portal closes or it resets and can’t be used again for 24 hours.”
He smiled at me and said, “So, if you bring me the small sum of 5,000 gp tomorrow, this alabaster portal key will be yours and I will teach you the ritual required to activate it.”
|Alabaster Portal Key
Wondrous item, artifact
This 3-inch tall alabaster statuette resembles a chess piece (a castle). Anyone who holds the key and knows the 10-minute activation ritual can activate the artifact. This person does not have to have any magical abilities. When activated, you create linked teleportation portals that remain open for the duration. Any creature or object entering either portal exits from the other portal as if the two were adjacent to each other. One portal is the one named in the activation ritual, which is a specific existing 4 foot wide by 8 foot tall stone archway which becomes filled with mist. This stone archway and the portal key are two parts of the same artifact. If you are not within 10 feet of the stone archway, the other portal is created at a location you choose within 10 feet of you and resembles a glowing arched gateway the same size as the stone archway. It is also filled with mist. If the key is activated when you are within 10 feet of the stone archway, it opens a portal in that archway and opens the remote portal at its previous location, allowing return travel to the point where that portal was last created.
The portals remain for one minute or you can close the portals early by touching the key to the side of either portal.
When within 10 feet of the stone archway, the key cannot be used to activate the portal until the day following its last use and at least 8 hours have passed. Otherwise, when not near the stone archway, the key can be used at any time.
The key must pass through the portal and be on the opposite side when the portal closes or it can’t be opened again for 24 hours.
I would like to hear your thoughts on this topic (or on this artifact).

Thoughts on 2016 and Plans for 2017
2016 was good for me as far as gaming goes. I was able to start playing again after a long time away from the table. I am now playing in a Dungeons and Dragons 5th edition game every Tuesday night and running one every Saturday. On Tuesdays, I am playing an orc barbarian in a Hoard of the Dragon Queen campaign. (I was playing a human bard until she got killed.) On Saturdays, I am the DM for an Age of Worms campaign. It was written for 3.5 but I am running it converted to 5th edition.
Earlier in 2016, I subscribed to Dungeon Crate and I have just started a subscription to RPG Crate. So far I like Dungeon Crate and will let you know what I think of RPG Crate. Reading the reviews, I have high hopes for it.
The response to this blog has been very encouraging. In January 2015 I had 58 followers. I now have 265 followers. Thank you very much! I will be adding my thoughts and ideas as well as reference material and updates to my player’s sheet. I didn’t work on my “Dragon Hunt” novel much last year, but I intend to get back to work on that this year. I expect there to be a lot of new material published for 5th edition this year. I am sure that I will be getting copies of all of the supplements, adventures, and expanded rulebooks, but I will continue to focus this blog on the Player’s Handbook, Dungeon Master’s Guide and Monster Manuel.
Happy new year. I hope all of your rolls are successes!

Classes with Class
In 2004 and 2005 Skip Williams (co-creator of Dungeons & Dragons 3rd Edition) put a series of articles on the Wizards website with tips on playing each of the various character types. Wizards of the Coast has moved them to their D&D Archives, but you can still find them there if you are diligent in your search.
These are an excellent reference. They were written for D&D 3.5 but even if you are running a fifth edition game you will find then a useful reference.
Here are direct links to them:
And here is a link to the 3.5 D&D Archives page:

Just as characters take damage when they fall more than 10 feet, so to do they take damage when they are hit by falling objects. I was using these house rules for 3rd edition and they still work for 5th edition. I would typically allow a character to make a DC 15 DEX saving throw to jump out of the way and take no damage.
Objects that fall upon characters deal damage based on their weight and the distance they have fallen.
For objects weighing 200 pounds or more, the object deals 1d6 points of damage, provided it falls at least 10 feet. Distance also comes into play, adding an additional 1d6 points of damage for every 10-foot increment it falls beyond the first (to a maximum of 20d6 points of damage).
Objects smaller than 200 pounds also deal damage when dropped, but they must fall farther to deal the same damage. Use this table to see how far an object of a given weight must drop to deal 1d6 points of damage.
|Object Weight||Falling Distance||Maximum damage|
|200 lb. or more||10 ft.||20d6|
|100-199 lb.||20 ft.||10d6|
|50-99 lb.||30 ft.||5d6|
|30-49 lb.||40 ft.||4d6|
|10-29 lb.||50 ft.||3d6|
|5-9 lb.||60 ft.||2d6|
|1-4 lb.||70 ft.||1d6|
For each additional increment an object falls, it deals an additional 1d6 points of damage up to the maximum damage. Objects weighing less than 1 pound do not deal damage to those they land upon, no matter how far they have fallen.

The only problem with a crossbow is that it takes so long to load most people can only make one crossbow attack each round. Because Player Characters aren’t “most people” they often are able to make multiple attacks each round. When the rules were written for fifth edition they attempted to restrict the number of times a crossbow could be fired and still allow for exceptions. Doing all of this and also keeping the rules simple and short created quite a bit of confusion. In my opinion, their subsequent attempt at clarifying the rules didn’t help all that much. This post represents my thoughts on the subject and how I deal with it using a couple of house rules.
General crossbow description: A crossbow has a wooden stock generally made from yew, ash, hazel or elm and coated with glue or varnish. The ‘bow’ is made of wood, iron or steel. The bow has a span of two to three feet. The crossbow string is made from hemp. The string has been soaked in glue as some protection against moisture. The string is pulled back by using a lever or winding a crank on a ratchet. This “cocking” of the crossbow is what gives a crossbow the “loading” property. The crossbow bolt is laid in a groove on the top of the stock and the trigger pulled. There are two or three notches to rest the thumb which can then be lined up with the bolt forming the crossbow sight. You add your dexterity bonus to crossbow damage to represent increased precision. A crossbow can be carried already loaded with a bolt.
Using a crossbow as an improvised weapon: If you have a crossbow in your hand and you are out of ammunition or it isn’t loaded (refer to loading below) you can still use your Attack action to try to hit somebody with it. As an improvised weapon it deals 1d4 bludgeoning damage. You don’t get your proficiency bonus on the attack but you can add your Strength bonus to both the attack and damage rolls. You could even throw it at them (range 20/60). That also deals 1d4 bludgeoning damage but rather than STR, you use your DEX bonus on attack and damage.
There are three types of crossbows listed in the Player’s Handbook. Here are my expanded descriptions.
Heavy Crossbow [Martial Ranged Weapon]: The string is pulled back by winding a crank on a ratchet. Because it is a heavy weapon, small size creatures have a disadvantage when attacking with it. This crossbow is not inexpensive (50 gp) but it does the most damage (1d10) and has the longest range (100/400). It requires two hands to load or to attack with this weapon. Although it weighs 18 pounds most characters should be able to carry it with just one hand.
Light Crossbow [Simple Ranged Weapon]: The string is pulled back by using a hinged lever which pulls the string into place. Despite its name, this weapon does not have the “light” property. It is the least expensive crossbow (25 gp) and does good damage (1d8) at a reasonable range (80/320). It requires two hands to load or to attack with this weapon, but it only weighs 5 pounds and can be carried in just one hand.
Hand Crossbow [Martial Ranged Weapon]: The string is pulled back by using a lever. It is the only crossbow with the “light” property. It can’t be used for two-hand fighting because that requires a light melee weapon and this is not a melee weapon, it is a ranged weapon. The “light” property might come into play with other abilities or DM rulings. For instance, a tight passage where non-light weapons have a disadvantage. This is the most expensive crossbow (75 gp) and does the least amount of damage (1d6). It also has the shortest range (30/120). As its name implies, it only weighs 3 pounds and can easily be held in one hand. You can shoot a hand crossbow with one hand but it requires two hands to load it. You can shoot a hand crossbow in each hand (if you are allowed more than one attack on your turn), but only if they are both loaded at the start of your turn.
Most of the confusion with crossbows comes from the wording of the Loading property and the Crossbow Expert feat.
|Loading. (PHB p. 147)|
|Because of the time required to load this weapon, you can fire only one piece of ammunition from it when you use an action, bonus action, or reaction to fire it, regardless of the number of attacks you can normally make.|
|Crossbow Expert (PHB p.165)|
|Thanks to extensive practice with the crossbow, you gain the following benefits:
• You ignore the loading quality of crossbows with which you are proficient.
• Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls.
• When you use the Attack action and attack with a one-handed weapon, you can use a bonus action to attack with a loaded hand crossbow you are holding.
I suggest replacing both of these with the house rules listed below.
Loading. (This replaces the loading property in the PHB) You cannot attack with a crossbow unless it has been loaded. The act of loading a crossbow consists of pulling the string back and securing it, drawing the crossbow bolt, and placing it into the slot on the weapon. The act of loading a crossbow requires the use of both hands. You can load a crossbow once per Attack action regardless of the number of attacks you are allowed to make in that action. Any round in which you do not make an attack, you can use an Attack action, or your free “interact with one object” activity to load a crossbow.
Crossbow Expert (replaces the Crossbow Expert feat in the PHB)
Thanks to extensive practice with the crossbow, you gain the following benefits:
- You gain proficiency with all crossbows.
- When you use the Attack action, every attack you make with a crossbow can include loading as part of the attack.
- Being within 5 feet of a hostile creature doesn’t impose disadvantage on any attack rolls.
- When you use the Attack action and attack with a one-handed weapon, you can use your bonus action to take one shot with a loaded hand crossbow you are holding in the other hand.
So, here are some examples of how the above house rules affect the game:
1) You can’t load any crossbow, even a hand crossbow, with a shield, hand crossbow, or any other weapon in your other hand.
2) You can use your “interact with one object” option to load (but not fire) a crossbow once a round provided you use both hands. But, you can’t do this and also load a crossbow as part of an Attack action that round.
3) You cannot load a crossbow as part of a Bonus action or a Reaction.
4) You cannot attack with a crossbow as a Bonus action or as a Reaction unless it is loaded.
5) If you are holding a loaded crossbow you can attack with it in any situation that permits you to attack, be that an Attack action, Bonus action, or a Reaction.
6) If you are allowed to use your Attack action to make two attacks, you can fire a crossbow that is already loaded and then load and fire it one more time in that action. You can only load it once per Attack action.
7) If you have two Attack actions, you can load and fire a crossbow once each action. In addition, you can fire it once at the beginning of your first Attack action if it is already loaded.
8) If you have the Crossbow Expert feat, you can load and fire a crossbow once for every attack you are allowed in an Attack action, but you cannot load a crossbow as part of a Bonus action or as part of a Reaction.

Simplified – fast and fun D&D
Rich Jones has created a variant to the D&D rules. Check it out HERE.
According to Rich “I have made a short, concise guide for playing a fast-and-fun-optimized variant of DnD that I have been playing with my friends, and … I use your pre-made character sheets as the recommended way to get started.”
I am glad that he found my stuff useful. Everyone should check it out and tell me what you think.

The Attack Action
With all of the different class features that allow multiple attacks, I am seeing a lot of confusion as to how many and what types of attacks a character can get on his turn.
“Attack” and “Attack Action” are two different things.
On your turn, you can move and take one action. A special ability, spell, or other feature of the game may allow you to also take a bonus action, and/or take a reaction. You may also interact with one object and do other simple activities. What is important here is that you can only take one action. One possible action you can take is called the Attack action. None of the other combat actions are an Attack action (Cast a Spell, Dash, Disengage, Dodge, Help, Use an object, Hide, Search, Readied action, Improvised action).
|Attack action: “With this action, you make one melee or ranged attack… Certain features, such as the Extra Attack feature of the fighter, allow you to make more than one attack with this action.” PHB, p192.|
This rule sounds fairly straight forward but combined with other rules, features, and options it can become a bit confusing. In certain situations, you make a melee or ranged attack when you Cast a Spell, take a Bonus action, or take a Reaction. In other situations when you take the Attack action you don’t make a melee or ranged attack. And, just because an action is called an “attack” doesn’t mean that you can perform that action when you use the “Attack action”.
This confusion could have been lessened a bit if the “Attack action” had a different name. Perhaps they could have called it the “Offensive action” or something. I am not going to do that here. However, it is important to know that when you read something in the Player’s Handbook, the Dungeon Master’s Guide or the Monster Manuel the wording is important. See if it says “Attack action” or just “attack”.
Partial list of things that you can do with an Attack action:
- Make a weapon attack with a melee weapon, ranged weapon, or improvised weapon. This includes drawing ammunition for use with a ranged weapon.
- Make an unarmed strike.
- Grapple a creature.
- Shove a creature.
- Two weapon fighting – When you use the Attack action to attack with a light melee weapon that you’re holding in one hand, the second attack, with a light weapon in your other hand, is a bonus action and not part of the Attack action.
- “Extra attack” – With many weapon-using classes you can gain the ability to attack multiple times, instead of just once. This feature can only be used when you take the Attack action.
- (Monks) “Flurry of Blows” can only be used (as a bonus action) after taking the Attack action.
- (Druid – while in beast form) Your weapon attacks, where the “weapon” might be a manufactured item or a natural weapon, can only be used when you take the Attack action.
- (Druid – while in beast form) If the creature has the Multiattack action, you may make the listed attacks rather than, or in place of, an Attack action.
Partial list of actions you CANNOT do as an Attack action:
- Cast a spell – even if that spell has you make a “range attack” or “melee attack” or “”spell attack”.
- Dash, disengage, dodge, help, use an object, hide, search, ready an action, or perform an improvised action.
- Make an opportunity attack. (This is done as a “reaction”)
The Attack action is not the only way you can attack. Some spell examples:
If you cast Eldritch Blast (with the Cast a Spell action), you make a ranged spell attack against a creature. This is an attack, but you’ve used the Cast a Spell action, not the Attack action to do so. As a result, abilities such as Extra Attack and Flurry of Blows won’t trigger.
If you cast Shocking Grasp (with the Cast a Spell action) you make a melee spell attack against a creature. Once again, you’ve used the Cast a Spell action, not the Attack action, so extra attack doesn’t apply.
Not all spells work that way, however. If you cast Shilleagh (as a Bonus action), you don’t immediately attack. Instead, it modifies how you attack (with the Attack action) for the duration of the spell, instead of using your Strength as the modifier for your attacks, you use your spellcasting ability score (normally Wisdom for druids).
Another wrinkle are the spells which have an ongoing effect. Vampiric Touch is one such spell – it allows you to make a melee spell attack when you cast it (with the Cast a Spell action), but the spell persists for up to a minute. Its text reads “Until the spell ends, you can make the attack again on each of your turns as an action”. Is this an Attack action? No, it isn’t. It’s a brand new type of action you get to use. Call it “Vampiric Touch action” if you like. These new actions allow you to attack, but they don’t use the Attack action. The trick to identifying them is that they read “as an action” or “use your action” to describe how they work. A few require the use of your bonus action instead.
All attacks are described in terms such as ranged spell attack or melee weapon attack. Each word means something.
“Ranged” attacks suffer disadvantage if you’re adjacent to an opponent, “melee” attacks do not. “Melee” attacks can be against any creature within your reach (generally 5 feet), while ranged attacks can be made against any creature within the stated range of the attack. In some cases, an attack form has two ranges; attacks at the longer range are made at a disadvantage.
If the wording says “melee weapon attack” you can do an unarmed strike. You add your strength modifier and your proficiency modifier (you are proficient with unarmed strikes) to your attack roll and it does damage equal to 1+ your strength modifier. But an unarmed strike is not a weapon. This means that any rule that applies to a “weapon attack” will apply to unarmed strikes but ones that apply specifically to a “weapon” do not.
“Spell” attacks use your spellcasting ability modifier, while “weapon” attacks use Strength (melee weapon) or Dexterity (ranged weapon). There are exceptions to this depending on the spell or type of weapon.
The word “attack” indicates that it is an attack roll, one of the three types of d20 roll in D&D. (The others are saving throw and ability check.) Attack rolls are different because a natural 1 is an automatic miss, while a natural 20 is an automatic hit and a critical hit. Both saving throws and ability checks don’t have special things happen on 1s or 20s.
One of the special cases is the fighter ability Action Surge. This allows you to take one additional action during your turn. If you use this to take the Attack action, you get as many attacks as you would if you took it for your first action. So, a 20th level fighter can get 8 attacks in a turn – four from the first Attack action and four from the second Attack action. You could then use your bonus action to attack with your off-hand weapon (Two-Weapon Fighting). Note that Action Surge does not give you an additional bonus action or move; only an additional action.
Another special case is the spell Haste. It allows an affected character to take an additional action each turn (not all actions are allowed). However, if you took the Attack action, you can only gain one additional attack with it – the Extra Attacks you might have don’t count.
Interestingly, this doesn’t stop you using Flurry of Blows or Two-Weapon Fighting, as both are part of bonus actions. You could use your first action to cast a spell, then your additional action from haste to make a single weapon attack with the Attack Action, then use your bonus action to make an off-hand attack with Two-Weapon Fighting since you’ve used the Attack Action during the turn.
Most of the rules and power descriptions use quite specific wording, but because the terms can be quite similar, it’s easy to get confused. “Attack action”, “As an action” and “Attack” mean three separate things, as do “When you make an attack” and “When you take the Attack action”. As long as you keep the differences in mind, you should be fine.
