Debilitating Dichotomy [two-actions] Feat 8Concentrate Cursebound Divine Mental Oracle Source Player Core 2 pg. 140
You reveal a glimpse of the impossible conflicts between the
divine anathema behind your
curse, forcing you to reckon with another's conflicts as well. You and one creature within 30 feet each take 9d6 mental damage with a basic Will save, and the target is stunned 1 if it critically fails its save. You get a degree of success one better than you rolled for your saving throw. At 10th level, and every 2 levels thereafter, the damage increases by 3d6.
Traits
Concentrate: An action with this trait requires a degree of mental concentration and discipline.
Cursebound: Abilities with this trait tighten your oracular curse's grasp on your soul in exchange for divine insights, giving you the cursebound condition. When you use a cursebound ability, you become cursebound 1, or if you were already cursebound, you increase the value of your cursebound condition by 1. As cursebound abilities are directly linked to your oracular curse, you can't use a cursebound ability if you don't have an oracular curse or if you are already at your maximum cursebound value. You can't mitigate or bypass the drawbacks of any cursebound ability with spells or other effects, and the effects of any cursebound ability end when you Refocus and remove the cursebound condition.
Divine: This magic comes from the divine tradition, drawing power from deities or similar sources. Anything with this trait is magical.
A creature with this trait is primarily constituted of or has a strong connection to divine magic.
Mental: A mental effect can alter the target’s mind. It has no effect on an object or a mindless creature.
