Order

Syntax: order <target> command

ORDER orders one of your charmed followers to perform any command.
The command may have arguments. You are responsible for the actions
of your followers, and others who attack your followers will incur the
same penalty as if they attacked you directly.

Most charmed creatures lose their aggresive nature (while charmed).

If your charmed creature engages in combat, that will break the charm, and
they will no longer follow your orders.
