You now have the killer instinct needed to tear off the skin of anyone.
Prerequisites: Member of the Flayer’s Circle
Effects: Whenever an enemy or ally scores a critical hit against another character, you are transported there. That character that had the crit hit rolled against it then loses 2d20-your Intelligence modifier life, and you gain that many temporary hit points until the end of the encounter.
Obtainable upon acheiving the sacrificer tier of the The Flayers’ Circle.
