You have signed a pact with Asmodeus, pledging your soul in exchange for unholy power.
Prerequisites: Evil alignment, you must sign a pact with Asmodeus or one of his agents.
Benefit: Three times per day, you can call upon the power of the Devil’s Pact to grant you a +2 profane bonus to any one d20 roll. You must declare that you are using this ability before the roll is made.
Special: If you die, you cannot be brought back to life by any means aside from a wish or miracle spell. Even if such a spell is employed, you return to life with three permanent negative levels.
You are familiar with pain, and have become adept at ignoring when needed.
Benefit: Whenever you have the sickened condition, you only take a –1 penalty on attack rolls, weapon damage rolls, saving throws, skill checks, and ability checks. Whenever you have the nauseated condition, you can take a move action and a standard action, but take a –4 penalty on any check associated with an action that requires a standard to complete (such as attack rolls, weapon damage rolls, some skill checks, caster level checks, and so on). When nauseated, you cannot take full-round actions.
You can consume the soul of a dying creature to heal the unholy.
Prerequisites: Channel negative energy 2d6, evil alignment.
Benefit: Whenever you make a coup de grace against a living creature, you can spend one use of your channel negative energy class feature as a swift action. If the creature dies and has at least as many Hit Dice as the number of dice you roll for channel negative energy, the channel heals all evil creatures (living and undead) within a 30-foot burst instead of its normal effect. If the creature does not have enough Hit Dice, the channel energy attempt is wasted.
