Charm Monster

Casting Time: 1 action
Range: 30 feet
Duration: 1 hour
You attempt to charm a creature you can see
within range. It must make a Wisdom saving
throw, and it does so with advantage if you or
your companions are fighting it. If it fails the
saving throw, it is charmed by you until the spell
ends or until you or your companions do
anything harmful to it.
