Dicipline Subordinate

As a leader, you demand absolute attention if necessary.  You issue an unarguable command to a creature, leaving it dumbfounded. If the target has 150 hit points or fewer, it is stunned. Otherwise, the spell has no effect.

The stunned target must make a Charisma saving throw at the end of each of its turns, to try and argue it's way out of your absolute reasoning. On a successful save, this stunning effect ends.
