Distracting Chorus

Create a psychic chorus in a 20-ft. radius sphere. Creatures of your choice must make an INT save. On a failure, they have disadvantage on concentration checks, cannot benefit from advantage on Perception checks, and subtract 1d4 from the first attack roll or ability check they make each turn.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
