Angel of Eiseth (Su)

The greatest sanguine angels earn the favor of the Erinyes Queen Eiseth, who transforms them into infernal servitors. At 10th level, a sanguine angel’s type changes to outsider (evil, extraplanar, lawful), and Hell becomes her native plane. She gains fire resistance 30, telepathy with a range of 50 feet, and the see in darkness universal monster ability. Ebon-feathered wings emerge from the sanguine angel’s back, granting her a fly speed of 50 feet with good maneuverability.
