An invoker who makes a pact with the Council of Fiends adds the following spells to her invoker spell list.
At 1st level, if the invoker damages a creature with an attack or a spell and that creature dies before the start of her next turn, she gains temporary hit points equal to her Constitution modifier + that creature’s total hit dice. If not lost, these temporary hit points last until the invoker regains spells.
At 5th level, as a supernatural ability, the invoker can gain a luck bonus equal to her Constitution modifier on one attack roll, saving throw, ability check, skill check, or weapon damage roll. She can use this ability once per day at 5th level and twice per day at 14th level.
Starting at 9th level, the invoker gains a permanent resist energy effect as a supernatural ability. Once per day, she can change the type of energy she resists as a full round action. After resisting damage equal to 5 x her level in a single day, the effect is suppressed until the invoker rests for at least 8 hours.
At 14th level, once per day, the invoker can send an enemy she damages with an attack or spell to the abyss to be judged by her otherworldly patron as a spell-like ability. A successful Will save (DC 10 + 1/2 the invoker’s level + her Constitution modifier) negates this effect. On a failed save, the creature disappears from combat until the start of the invoker’s next turn. Upon its return, the creature suffers 1d6 damage per invoker level. This is a conjuration (teleportation) effect.
