At level 5, Regain health points equal to charisma modifiers plus character level. It can be used again after a long rest.

At level 10, Wraths can become an unstoppable force in battle. While in combat, if Wraths are reduced to 0 hp, they can continue to fight and take damage into the negative. While in this state, their bodies start glowing with cracks of divine radiance, and they gain an advantage on all melee attacks. Each enemy they kill or assist in killing will grant them 3hp. If they don't attack for three rounds or combat ends and they don't have at least 1hp, their bodies will slowly disintegrate, and they will fade away. If they survive, they gain four levels of exhaustion.

At level 15 and after a long rest, Wraths will grow an additional pair of arms, allowing them another melee or ranged attack per turn. However, if each hand wields a weapon, then any two-handed weapons attack is at a  disadvantage.
