Darkvision Aasimar have darkvision 60 ft. (they can see perfectly in the dark up to 60 feet.)
Deathless Spirit Particularly strong-willed aasimars possess celestial spirits capable of resisting the powers of death. They gain resistance 5 against negative energy damage. They do not lose hit points when they gain a negative level, and they gain a +2 racial bonus on saving throws against death effects, energy drain, negative energy, and spells or spell-like abilities of the necromancy school. This racial trait replaces celestial resistance.
Scion of Humanity Some aasimars' heavenly ancestry is extremely distant. An aasimar with this racial trait counts as an outsider (native) and a humanoid (human) for any effect related to race, including feat prerequisites and spells that affect humanoids. She can pass for human without using the Disguise skill. This racial trait replaces the Celestial language and alters the native subtype.
Skilled Aasimar have a +2 racial bonus on Diplomacy and Perception checks.
Spell-Like Ability (Sp) Aasimars can use daylight once per day as a spell-like ability (caster level equal to the aasimar's class level).
