Crimson Banquet

Draw power from wounded creatures nearby. Living creatures of your choice in the emanation that are below half hit points make CON saves, taking necrotic damage on a failure or half on a success. You regain hit points equal to your CHA modifier for each creature that fails, up to five creatures.

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