Iron Flask

You can use an action to speak the flask's
command word, targeting a creature that you can
see within 60ft that is native to another plane.
The target must succeed on a DC 17 Wis save or
be trapped in the flask. If the target has been
trapped by the flask before, it has advantage on
the save.
You can use an action to remove the flask's brass
stopper and release the contained creature, which
is friendly and obeys your commands for 1 hour,
then may act freely.
