Damned (Ex)

When a demoniac is killed, his soul is instantly claimed by the Abyss. In time, the demoniac’s soul is transformed into a demon appropriate to the greatest sins the demoniac gloried in while he lived. Any character attempting to resurrect a slain demoniac must succeed at a caster level check equal to 10 + the demoniac’s level or the spell fails. That character cannot attempt to resurrect the demoniac again until the following day, though other characters can attempt to do so if they please.

Demonic Mark (Ex): A demoniac bears the sign of his chosen demon lord as a tattoo-like brand somewhere on his body.

Once per day, a demoniac can call upon the profane power of this mark to power a spell as he casts it. Doing so causes the spell to gain the chaotic and evil descriptors, and causes the spell not be expended as it is cast, allowing the demoniac to cast the spell again at a later point in the day.
