Iron golem form (shifter)

Iron golem: Forged from solid iron, the crafting of these mighty juggernauts often requires the expertise and master craftwork of either dwarven blacksmiths or gnome artificers.

Special Abilities
An iron golem is immune to critical hit, death magic, disease, level drain, ability drain, mind-affecting, paralysis, poison, and sneak attack.

Builder's note
This polymorph lacks a scripting constant; it must be referred to by the number 90.
