Zone of Truth

Action • 60ft/15ft • V, S • 10 min {bull} CHA Save
Until the spell ends, a creature that enters the
spell's area for the first time on a turn or starts
its turn there must make a CHA Save. On a
failed save, a creature can't speak a deliberate lie
while in there. You know whether each creature
succeeds or fails on its save. An affected creature
is aware of the spell an can be evasive, limited
by the boundaries of the truth.
