Tide Turner

Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Turn the Tide. When a friendly creature you can see within 30 feet of you misses an attack roll or fails a saving throw, you can use your Reaction to turn their setback into a sudden opening. You roll a 1d6 and add it to the creature's total, potentially turning the failure into a success. If this addition turns the roll into a success, the tide of battle shifts: the chosen creature can immediately use its Reaction to either make one weapon attack or move up to half its Speed without provoking opportunity attacks. You can use this feature a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
