You are able to flare your alignment aura to debilitate your foes.
Benefit(s): Once per day, when you channel energy, you are also able to cause your divine aura to flare in a display of overwhelming force, affecting all good creatures within the aura (if you channel negative energy) or all evil creatures in the aura (if you channel positive energy). This effect is in addition to the normal effects of channeling energy.
When you flare your aura, select from one of the following options based on the strength of your alignment aura. You can select a lower-strength effect.
Overwhelming: Affected creatures must succeed at a Fortitude save (DC = 10 + 1/2 your class level in the class granting you the channel energy ability + your Charisma bonus) or be staggered for 1d4 rounds.
