Chorus of Masks

For the duration, willing creatures wearing your masks in the emanation can communicate telepathically with you and each other. Once per round when a mask wearer uses a stored power, another mask wearer in the emanation gains advantage on the next attack roll, ability check, or saving throw it makes before the start of its next 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.
