Inquisitor Ghiza is a character in Elden Ring. He is found in the second floor dining hall of the Volcano Manor and invades the Tarnished when they first step foot there. He carries a large wheel weapon - an arm of the wheeled variant of an Abductor Virgin. He wears robes with a bandaged face, arms, and legs.
Defeating him will reward the Tarnished with his weapon (also known as the "Pizza Cutter" given its shape and spinning attack).
