Celestial Sorcerer Aura

 
Prerequisite(s): Celestial Sorcerer Heritage, Sorcerer Level 1+
 
Benefit: As a standard action, you can expend a spell slot to generate a righteous aura of menace that affects all hostile creatures in a 20-foot radius around you. All your opponents within this area must make a Will save (DC 10 + the level of the spell slot expended + your Cha modifier). On a failed save, a creature takes a -2 penalty on attack rolls, checks, and saves for 24 hours or until it successfully hits you. A creature that resists or breaks this effect cannot be affected by it again for 24 hours. This is a supernatural ability.
