Porkalator

Kirke will use the Porkalator spell to attempt to temporarily turn the target into a hog. This target is probably going to be You. This will meld your armour, weapon, and rings into your body, suppress suppressible mutations, and prevent you from casting spells until it wears off.

As with any other non-damaging enchantment, high Magic Resistance will help you to avoid becoming porkalated.

Only natural, demonic, or holy creatures can be affected by this spell (so you're safe if you're undead or in lichform). Demonic creatures will be turned into hell hogs; holy creatures into holy swines.
