Surrogate Spellcasting

WIS 13, nonhumanoid or nonhumanlike form,

You complete the verbal and somatic components of spells by substituting vocalizations and gestures appropriate to your shape. You must still have suitable appendages and vocal organs. For example, a giant eagle could substitute screeches and waves of its talons for the normal verbal and somatic components of a spell. You can use any material component or focus that you can hold. This feat does not permit the use of magic items by a creature whose form could not ordinarily use them, and you do not gain the ability to speak if you cannot already.
