You attempt to command a creature to obey one order you give it. The creature must make a Wisdom saving throw, if you or your allies are fighting it, it has disadvantage on the saving throw.

If it fails, a small arcane mark appears on the creature, and it feels magical energy enter it's body. The creature does not have to understand you for the spell to work. While this spell is in effect the creature is fully in control of itself. It can choose to obey or disobey your order. If it obeys your order, nothing happens. If the creature chooses to disobey your order the mark on it's body will break, and the creature takes 10d12 force damage as the magic that entered it's body retaliates, and the spell ends. When the spell is cast, a creature is aware that if it disobeys the order, that there are serious repercussions for it.

You can command the creature to do anything it is capable of doing such as, "Attack you friends" or "Don't move". As a free action on the following turns, you can give the creature another order, rendering the previous order null and void.
