Assist

You rally, guide or otherwise create an opportunity for a friendly creature you can see within 30ft, enabling them to act in response to you. The creature can immediately use its reaction to make one melee or ranged attack or move up to half its movement speed without provoking opportunity attacks.

At Higher Levels: You can target one additional creature when you reach 5th level (2 targets), 11th level (3 targets), and 17th level (4 targets).
