Khadidas

From Glen Cook Wiki

The entity which takes over Goblin's corpse after the little wizard dies stabbing the goddess Kina. Khadidas, or "slave of Khadi", shares Goblin's body with the imprisoned soul of the wizard. It pretends to be Goblin until it has a chance to kill the imprisoned and crippled Narayan Singh and help the Daughter of Night fulfill its mission.

Khadidas is somewhat more powerful than Goblin was as a wizard, capable of shooting brown urine-colored energy bolts and somehow making Goblin's body highly resistant to regular weapons; it is able to regenerate Goblin's destroyed eyes in a matter of days. However, it can be defeated by more powerful sorcery (Soulcatcher and Tobo both easily overcome it) and is highly vulnerable to the Black Spear.

Khadidas is forced into submission by One-Eye's hat, which he enchanted specifically to help Goblin's spirit emerge from its imprisonment. While wearing the hat, Khadidas is subdued by Goblin's real personality. It perishes when Goblin sacrifices himself to kill Kina with the Black Spear.
