Irrepressible Soul (Su)

Your true self can't be buried beneath disguises or magical effects. Once per round as a free action, you can expend one use of mythic power to attempt to end one effect that is currently affecting you. When you use this ability, you make an additional saving throw against the effect at its original DC, even if one would not normally be allowed. This ability can end only polymorph effects, charm and compulsion effects, domination effects, illusion effects that change your appearance, and any effects that control or conceal your true identity. If you succeed at the second saving throw, the effect immediately ends.
