ObedienceEvery day you must lie to someone for your own personal gain (this cannot be the same person more than once a week). Additionally, once per week, you must write down a new secret that you have learned about someone else and burn it as a sacrifice to Mephistopheles. Gain a +4 profane bonus to Diplomacy checks attempted against targets whose attitudes are unfriendly or worse.

1: Fool Maker (Sp) charm person 3/day, undetectable alignment 2/day, or suggestion 1/day
2: Persecutor (Ex) You can use your Bluff skill to demoralize opponents and influence an opponent’s attitude as though it were the Intimidate skill. The effects function the same. Additionally, you may use the Knowledge (religion) skill on any check related to knowing about or interpreting the law—including infernal contracts.
3: Charming Liar (Su) Whenever you use the Bluff skill, you can use the Diplomacy skill to influence an NPC’s attitude at the same time. Both skill checks are made independently, so even if one fails, the other might succeed—suggesting an obvious but charming falsehood or an aggravating but convincing lie. Additionally, any spell of the charm subschool that you cast has its DC increased by 2.
ExaltedSource Pathfinder #102: Breaking the Bones of Hell pg. 75
1: Faith Taker (Sp) unseen servant 3/day, detect thoughts 2/day, or glibness 1/day
2: False Priest (Su) You gain a +4 bonus on Disguise checks to pass as a worshiper of another deity and can cast spells using holy symbols other than your own. Additionally, for a number of hours per day equal to your Charisma modifier (minimum 1), you can disguise your alignment. By spending a standard action, you hide your true alignment and instead detect as being of the same alignment as the deity whose holy symbol you are wearing.
3: Revoke Healing (Su) A number of times per day equal to your Charisma modifier (minimum 1), you can deal damage to a creature in your line of sight that you have magically healed within the past 24 hours. The damage equals the amount restored by the highest-level spell with the healing descriptor that you can cast. This may result in you causing more damage than you healed. The damage occurs in a single round. In the case of healing spells that heal over multiple rounds, only healing provided in the first round is counted when determining damage.

1: Trust Breaker (Sp) doom 3/day, eagle’s splendor 2/day, or keen edge 1/day
2: Spectacular Rival (Su) A number of times per day equal to your Charisma modifier (minimum 1), you can add your Charisma modifier (minimum 1) to your combat maneuver bonus.
3: Fatal Choice (Su) Once per day, upon defeating an opponent, you can heal it and attempt to force it to obey you. As soon as you reduce a living creature to –1 or fewer hit points, you can force it to attempt a Will saving throw with a DC equal to 10 + your Hit Dice + your Charisma modifier. If it succeeds, it begins dying as normal. If the target fails, it is restored to 1 hit point and is affected as per the spell charm monster. The target can willingly fail this saving throw. This effect lasts for a number of minutes equal to your Charisma modifier (minimum 1). At the end of this period, the target can behave as normal.
