Blood Moon Feast

Draw blood-force from the battlefield. Living creatures of your choice in the emanation make CON saves, taking necrotic damage and losing the ability to regain hit points until the start of your next turn on a failure. You regain hit points equal to half the highest damage dealt to one target.

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