Discordant Performance

Hostile creatures of your choice in the emanation that can hear you must make a WIS save. On a failed save, a creature is charmed or frightened by you, your choice, for the duration. While affected, it has disadvantage on attack rolls and saving throws, and it cannot benefit from advantage. A creature repeats the save at the end of each of its turns, ending the effect on a success.

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