Cursed King

Cursed King is an Arcane kit with fast slashes, area fire, and domain control. October 9 odds are 0.04% normal and 0.4% lucky. Pairing it with Immortal Sovereign grants a damage bonus with no printed percent. Launch notes used Sukuna Fingers as an evolution example for a weapon named Sukuna. That may be this kit. It is not confirmed, so Sukuna remains its own entry.

Roll it in the Arsenal at the Arcane odds on the October 9 table.

Pair with Immortal Sovereign for the damage bonus. If an evolve prompt asks for fingers, compare the tooltip with the Sukuna entry before you grind.
