Bloodline Dominion

Touch a willing creature, fresh blood, or bloodline relic. For the duration, you can sense the direction to living blood relatives of that target within 10 miles, identify bloodline curses or inherited magic, and grant one willing blood relative advantage on saves against disease, poison, necrotic damage, or blood magic.

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