My turn my turn!
Hide:
With the Hide action, you try to conceal yourself. To do so, you must succeed on a DC 15 Dexterity (Stealth) check while you're Heavily Obscured or behind Three-Quarters Cover or Total Cover, and you must be out of any enemy's line of sight; if you can see a creature, you can discern whether it can see you. A distracted creature may not have line of sight to you even if it normally would.
On a successful check, you have the Invisible condition. Make note of your check's total, which is the DC for a creature to find you with a Wisdom (Perception) check.
Hidden: while hidden from a creature, it is not aware of your location. It is possible to be hidden from some creatures and not others.
You stop being hidden immediately after any of the following occurs: you make a sound louder than a whisper; an enemy finds you by taking the Search action, moving into your location, an enemy has unblocked line of sight to you during its turn, or other situations the DM judges appropriate; you make an attack roll; you cast a spell with a Verbal component.
