You can blast undead with incarnum-purified positive energy. When you use this feat, your brow is enveloped in a brilliant blue corona.
Prerequisite: Con 13, turn undead class feature.
Benefit: Once per day, you can invest essentia into this feat. When you make turning checks, any undead whose HD are low enough to be potentially turned or destroyed by your checks are also dealt 1d8 points of damage per point of essentia invested. Once the amount of essentia invested is chosen, it cannot be altered and remains invested for 24 hours.
You gain 1 point of essentia.
