Ventriloquism

This spell alllows you to make it sound as if your voice seems to originate from another location, such as another creature, a statue, or behind a door.  The effect must occur within range, and you can mimic up to four additional voices or sounds, although not simultaneously.  You are limited to the languages you speak and other simple sounds that can be reproduced such as screams, banging on wooden objects, or even footsteps.  A creature hearing the sound can take an action to focus on it, and make a successful Wisdom saving throw to discover the ruse.
