Rhythm of Victory

Creatures of your choice in the emanation that can hear you gain +10 ft. speed. Once per round, when an affected creature reduces a hostile creature to 0 hit points or scores a critical hit, another affected creature may use its reaction to move up to its speed and make one weapon attack.

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