Animal Imitation

This spell allows the caster to perfect mimic the sounds of any natural animal or beast, and will be audibly indistinguishable from the real thing. The caster can make a variety of such sounds, such as the mating call of an elk, the growl of an angry bear, or even a pack of wolves chasing a frightened rabbit. The caster can make a wide range of animal sounds for the duration of the spell, although he can only sound like one animal at a time. The caster must have heard the sound(s) to be imitated at least once.

When cast using a spell slot of 2nd level or higher, the duration increases by 10 minutes for each slot level above 1st.
