Nazastarool

Nazastarool is an undead encountered during Shilo Village quest. He has three forms; the first being a level 91 Zombie, second a 68 Skeleton and finally a 93 Ghost. All three forms have to be fought during the quest. A very easy way to kill him is to either range or use magic on him, as he can get stuck behind obstacles.

When defeated, he curses the player and disappears.

Crumble Undead does not affect Nazastarool even though it turns to a zombie. Note that friends can kill him for you in the quest (this may be a glitch, however).
