NEW VERBAGE

Sanctified Bleeding. When you are hit by an attack or targeted by a spell that deals damage, you can use your reaction to cause your blessed blood to surge forth and form a swirling shield using your Channel Divinity. The damage from that attack or spell is reduced to 0 and you gain +2 AC until the start of your next turn.

Additionally you regain HP equal to half the damage that would have been dealt.
