Soul Power | Pathfinder Wrath of the Righteous Wiki

A dark elementalist uses the souls of others to protect herself from the dangers of burn. She can't choose to accept burn if doing so would raise her total number of points of burn above 3. However, a number of times per day equal to her Intelligence modifier, as a full-round action she can gather up the souls of dead creatures with HD sum equal to or higher than her character level. When she does, some of her existing burn is unloaded into the departing souls, racking it with unspeakable torment, but reducing her current burn total by 1 point.
A dark elementalist gains attack and damage bonuses from elemental overflow based on how many times that day she has successfully used soul power to rack souls, rather than based on her current burn total. For instance, a 9th-level dark elementalist who had used soul power three or more times during the course of the day would add a +3 bonus on attack rolls and a +6 bonus on damage rolls. A dark elementalist does not gain size bonuses to physical ability scores or a chance to ignore critical hits and sneak attacks from elemental overflow.
This ability alters burn and elemental overflow and replaces internal buffer.
