The "Attack action" is a specific action; attacks are anything with an attack roll.
What is the Attack action?
The "Actions in Combat" section of the Player's Handbook (PHB, page 192) states (emphasis mine):
When you take your action on your turn, you can take one of the actions presented here, an action you gained from your class or a ...
You were quoted the rules incorrectly.
First, Eldritch Blast has a casting time of 1 action (PHB p.237). You've only got one action on your turn, so you can only cast Eldritch Blast once. ("Off the shelf," that is. There are features, like the Sorceror's Quickened Spell, Action Surge, or even time stop that might change this.)
Boom. That's it. They ...
Cunning Action absolutely does let you Dash again, but Dash doesn't work quite like you're remembering (PHB, p. 192):
When you take the Dash action, you gain extra movement for the current turn. The increase equals your speed, after applying any modifiers.
Speed and movement are separate concepts in 5e. Usually your allowed movement for the turn = your ...
Your players are right. An unconscious character can consume a potion administered by another player.
This ruling is held up by the Sage Advice Compendium (p. 21):
Can potions be administered to unconscious characters as an action?
Yes, you can administer a potion to someone else as an action (DMG, 139).
As with all things, it's perfectly allowable to ...
Anyone wielding two light weapons can attack with one weapon and use a bonus action to make an offhand attack.
The Rogue's having Cunning Action as an option does not prevent them from instead choosing other bonus actions. The restriction only applies to Cunning Action itself - if the Rogue chooses to use Cunning Action, only Dash, Disengage, and Hide can ...
Realistically, weapons too large or unwieldy to sheathe were simply carried in-hand until they were used. Realistically, anyone wielding one had a sidearm sheathed on their hip, as well—which is what swords often were, something to carry when you couldn’t bring your weapon-of-war around, or if you lost that in a battle.
Also, just to be clear, people ...
Yes, a fighter gets their extra attack when using action surge
Action surge gives you an extra action on your turn:
On your turn, you can take one additional action on top of your regular action and a possible bonus action.
There is no restriction on what this action can be used for. Using it to take the Attack action would indeed then trigger Extra Attack ...
No, there are no ways to gain an additional bonus action. Note that I didn't say no others - the Haste spell doesn't give you one either.
Until the spell ends, the target [...] gains an additional action on each
of its turns. That action can be used only to take the
Attack (one weapon attack only), Dash, Disengage, Hide,
or Use an Object action.
The caster continues casting the spell.
Taking the same quotes from @Xirema's answer, we have the following for casting spells with a long casting time:
Certain spells (including spells cast as rituals) require more time to
cast: minutes or even hours. When you cast a spell with a casting time
longer than a single action or reaction, you must spend ...
No. The Amazing Light Speed Horse™ cannot move an infinite distance
(And what distance it does move without taking the dash action is at a speed of at most movement per round, and with the dash action is 2×movement per round.)
Per the definition of movement from the Basic Rules v 0.3, page 63, and also from the Player's Handbook, page 181:
Every character ...
Drawing an arrow from a quiver is part of the action of attacking with a longbow
Longbows (and all ranged weapons that fire projectiles) have the ammunition property which says:
Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon).
Thus, it is not an object interaction or ...
No, you can't do that. Purely mechanical events like "at the end of my turn" or "before your turn" are not legal triggers (PHB, p. 193, emphasis mine):
[…] First, you decide what perceivable circumstance will trigger your reaction.
That means that only things that your character could perceive make for legal triggers.
So, say we have two PCs ...
No, the shove cannot be taken before the attack.
The first bullet of the Shield Master feat is:
• If you take the Attack action on your turn, you can use a bonus action to try to shove a creature within 5 feet of you with your shield.
Jeremy Crawford has changed the rules on this recently.
In early 2015 he posted on Twitter with the following.
The rule for bonus actions says:
You choose when to take a bonus action during your turn, unless the bonus action's timing is specified, and anything that deprives you of your ability to take actions also prevents you from taking a bonus action.
So unless the bonus action specifies that you have to take it at a specific time, you can take the bonus ...
No, drawing a weapon does not take an action. Nor does picking up a dropped weapon. Both answers are found in the "Interacting with Objects Around You" sidebar on page 190 in the Player's Handbook (PHB):
Here are a few examples of the sorts of thing you can do in tandem
with your movement and action:
draw or sheathe a sword
pick up a ...
The misconception here is that you don't have "a bonus action" just lying around that you "fill" with a Bonus Action. When something says that you can use a bonus action, that means you have that bonus action lying around. Any time a rule talks about having or using a bonus action, that is both making it available and permission to use it, not just ...
Rules as Written, the Spellcaster would lose the spell
This is relatively straightforward. The rules for spellcasting state unambiguously that a caster casting a spell with a long casting time must use their action each turn to cast it:
Certain spells (including spells cast as rituals) require more time to cast: minutes or even hours. When you cast a spell ...
There's nothing in the Ready action description that would prevent readying Disengage. When you ready an action you:
decide what perceivable circumstance will trigger your reaction. Then, you choose the action you will take in response to that trigger, or you choose
to move up to your speed in response to it.
The perceivable circumstance is that the ...
On your turn, you can move and perform an action. The ready action is, as you point out, an action like any other. This means that on your turn you can move and take the ready action.
The Ready Action
The ready action allows you to react to a specific, "perceivable circumstance."
To do so, you can take the Ready action on your turn so ...
Treat turns as simultaneous
To ensure better coordination, the DM might describe turns as simultaneous (they are, apparently).
Example 1. The cleric casts Turn Undead. The DM says, which undead were affected by describing them starting to flee. It doesn't matter that, mechanically, they will do only in their turn - they already have made their saving ...
No it doesn't give you another bonus action. The optional part is that if you haven't used your bonus action that turn you can still use it after the Action Surge (AS).
So it could be:
Action → Bonus Action → AS Action
Action → AS Action → Bonus Action
To quote the rules:
You can take only one bonus action on your turn, so you must choose which ...
There are no specific rules vis a vis how a character starts combat. D&D5E attempts to avoid that kind of specificity when basic logic and reasoning will do:
If the character is hanging out in a tavern, his hands are empty... or full of food. Utensils are Improvised Weapons, by the way.
If the character is hanging from a chandelier, at least one hand ...
I would say that Alex can no longer finish their turn, as they are immediately Stunned and therefore incapacitated.
A stunned creature is incapacitated (see the condition), can’t move, and can speak only falteringly.
To me, this is no different than if the Monk had attacked normally, without using the Stunning effect, and reduced Alex ...
The maximum number of spells a character can cast in a round is 3. You can only take 1 reaction per round, although some monsters have an ability that allows them to ignore this restriction.
You can't cast another spell during the same turn, except for a cantrip with a casting time of 1 action.
This means that you can cast a bonus action spell and a ...
RAW, the use of Lay on Hands is heal HP, or cure disease. The keyword in the phrase is "alternatively" (emphasis mine).
Alternatively, you can expend 5 hit points from your pool of healing to cure the target of one disease or neutralize one poison affecting it.
The idea is that in combat, the process of using Lay on Hands only ...
It probably doesn't break the game.
Ready actions that fail aren't (or shouldn't be) so enormously common that this is going to seriously change the game. At worst, this makes readied actions slightly more attractive when the situation is fluid and it's hard to determine what exactly you might want to react to.
That said, it's not a huge thing, but I don't ...
Unfortunately, it would require your action. You can sheath a weapon or draw a weapon using your free object interaction, but not both. (Addendum: The Dual Wielder feat allows you to draw 2 weapons or sheath 2 weapons using a single object interaction. Note that this does nothing to fix your problem, it just seemed worth mentioning.)
A Rogue with the Thief ...
No. Actions cannot be traded for bonus actions.
Various class features, spells and other abilities let you take an additional action on your turn called a bonus action.
You can take only one bonus action on your turn, so you must choose which bonus action to use when you have more than one.
You choose when to take your bonus action during your turn, unless ...
I don't believe allowing this would even be a house rule, the rules support it as-is.
The action enabled by the Healer feat is just a new use for an object and, therefore, is still technically the Use an Object action to execute, and would be usable with a bonus action by someone with Fast Hands as a result.
See also the description of the Use an Object ...
