- Similar to Holmgang, if the dark knight dies while the action is active, they will enter a zombie-like state with 1 HP for ten seconds. For ten seconds, the dark knight must be healed for an amount equal to 100% of their HP, e.g. if they have 15000 max HP, they must be healed for at least 15000 to exit the zombie state.
