As the polymorph incantation, except that you change the subject into a Small or smaller animal of no more than 1 HD (such as a dog, lizard, monkey, toad, or viper). If the new form would prove fatal to the creature (such as polymorphing a landbound target into a fish), the subject gets a +4 bonus on the save. If the incantation succeeds, the target must also make a Will save. If this second save fails, the creature gains the Intelligence, Wisdom, and Charisma scores of its new form. It still retains its class and level, hit points, base attack bonus, base save bonuses, allegiances, extraordinary abilities, supernatural abilities, and spell-like abilities, as well as any spellcasting ability possessed.
Note that incorporeal or gaseous creatures are immune to being polymorphed, and a shapeshifter (such as a werewolf) can revert to its natural form as a move action.
Material Component: Laboratory equipment and alchemical supplies (purchase DC 25).
Focus: Part of the kind of creature that the target will turn into, such as a hair, scale, or feather. If you have a living, helpless creature that can serve as a model for the target creature, you gain a +2 bonus on the Knowledge (arcane lore) checks required for this incantation.
Secondary Casters: 12 required (not including the primary caster).
Failure: Reversal on all secondary casters, using the same saving throw DC.
