With this spell, the caster can bestow upon an animal the ability to speak any specified language known by the caster. The animal can talk to any creature within normal speaking distance that understands the bestowed language, though the animal's intelligence remains the same as it was prior to casting. The affected animal is basically well disposed toward the caster while the spell lasts.
The material component is mistletoe.
Notes: Rare for druids and similar priests. (Updated from Polyhedron Newszine.)
