Special Attack/Defense: The avatar's skin is very tough with scales of steel, and edged weapons below +2 enchantment are 25% likely to break when struck against it. The avatar can smell gnomes up to a mile away, and is permanently enraged by gnomes if able to see or fight them. In his enraged state, Kurtulmak's avatar cannot be forced to leave combat with a gnome or a group of creatures including gnomes by any means, including all magical means. He has an aura of fear which forces enemies within 20 feet to save versus spells (-4 penalty for gnomes) or flee in panic. His tail has a poisonous stinger, and he carries a spear +4.
