Forgedawn's Armor of Warmth

You choose a willing creature who would be hit by an attack, but before damage is dealt. Until the spell ends, the target is enveloped by a cloak of comforting warmth, and the target's AC increases by 1d8.

If the attack misses, the target gains 1d10 hit points.

Additionally, if the attack still hits, the incoming damage is reduced by 1d12.
