Zone of Truth

Duration: 10 minutes
You create a magical zone that guards against
deception in a 15 ft radius sphere within range.
A creature that enters the spell's area or starts it's
turn there makes a Cha save. On a failure, a
creature can't speak a deliberate lie while in the
radius. You know whether each creature succeeds
or fails on it's save. An affected creature is aware
of the spell and can avoid answering questions, it
can be evasive in its answers as long as it remains
within the boundaries
