The Gift of Harmony

You and allies within 10 feet of you add your proficiency bonus to saves against fear and charm effects.

Once per short rest you can use a reaction to invoke the gift of Tranquility when a creature targets you with an attack. The creature must make a wisdom saving throw DC 8+ PB + Wis mod. On a failure that creature is incapacitated. It can repeat this save at the end of each of its subsequent turns.
