Archsanguine Form

For the duration, you become an archsanguine vessel. You are immune to necrotic damage, bleeding, mundane disease, and poison in the blood. Your Sanguinomancy powers treat necrotic immunity as resistance for creatures with blood, and once per turn when you deal necrotic damage with Sanguinomancy, regain hit points equal to your WIS modifier.

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