You force the subject to assume the form of a Small or smaller animal of no more than 1 HD. The subject takes on all the statistics and special abilities of an average member of the assumed form in place of its own except as is normal for the polymorph subschool and as follows.
If the assumed form would prove fatal to the creature — such as if you polymorph a landbound subject into a fish, or an airborne subject into a toad — the subject gains a +4 bonus on the save.
