You make a melee or ranged weapon attack.
You cast a cantrip or a spell of 1st level or higher. See the spell's casting time.
You gain extra movement equal to your speed (plus any modifiers) for the current turn.
Your movement doesn't provoke opportunity attacks for the rest of the turn.
Until the start of your next turn, any attack roll made against you has disadvantage if you can see the attacker, and you make Dexterity saving throws with advantage. You lose this benefit if you are incapacitated or if your speed drops to 0.
You help one creature with a task, giving that creature advantage on the next ability check it makes for that task. Or you distract one creature within 5 feet of you, and the next attack roll that an ally of yours makes against that creature has advantage.
Whichever option you choose, the advantage goes away once used or when your next turn starts.
You make a Dexterity (Stealth) check in an attempt to become hidden-unseen and unheard.
You wait for a particular circumstance before you act, which lets you act using your reaction before the start of your next turn. You must decide in advance (a) what perceivable circumstance will trigger your reaction and (b) the action you will take in response to that trigger.

If you run out of breath or you're choking, you can survive for a number of rounds euqal to your Constitution modifier (minimum of 1 round). At the start of your next turn, you drop to 0 hit points and are dying, and you can't regain hit points or be stabilized until you can breathe again.
