The powers of the Abyss can vary radically, even for similar fiends.
Associated Bloodline: Abyssal.
Whenever you cast a spell that deals hit point damage, one target of your choice affected by the spell takes 2 additional hit points of damage. This ability has no effect on spells that do not deal hit point damage (such as ability score damage).
Flight is often the key to survival.
Wings of the Abyss (Su): At 9th level, you can sprout leathery wings and fly for a number of minutes per day equal to your sorcerer level, with a speed of 60 feet and good maneuverability. This duration does not need to be consecutive, but it must be used in 1-minute increments.
This bloodline power replaces strength of the abyss.
