(Ex) The claws of an underworld dragon are made of adamantine, and have the qualities of a weapon made from that material.
(Ex) A very young and older underworld dragon can see perfectly in smoky conditions (such as those created by pyrotechnics).
(Su) A graveknight constantly exudes an aura of intense evil and negative energy in a 30-foot radius. This aura functions as the spell desecrate and uses the graveknight's armor as an altar of sorts to double the effects granted. The graveknight constantly gains the benefits of this effect (including the bonus hit points, as this aura is part of the graveknight's creation). In addition, this miasma of fell energies hinders the channeling of positive energy. Any creature that attempts to summon positive energy in this area—such as through a cleric's channel energy ability, a paladin's lay on hands, or any spell with the healing subtype—must make a concentration check with a DC equal to 10 + 1/2 the graveknight's Hit Dice + the graveknight's Charisma modifier. If the character fails, the effect is expended but does not function.
This spell imbues an area with negative energy. The DC to resist negative channeled energy within this area gains a +3 profane bonus. Every undead creature entering a desecrated area gains a +1 profane bonus on all attack rolls, damage rolls, and saving throws. An undead creature created within or summoned into such an area gains +1 hit points per HD.
If the desecrated area contains an altar, shrine, or other permanent fixture dedicated to your deity or aligned higher power, the modifiers given above are doubled (+6 profane bonus to negative channeled energy DCs, +2 profane bonus and +2 hit points per HD for undead created in the area).
Furthermore, anyone who casts animate dead within this area may create as many as double the normal amount of undead (that is, 4 HD per caster level rather than 2 HD per caster level).
Aura of Evil:
The power of an antipaladin’s aura of evil (see the detect evil spell) is equal to his antipaladin level. A paladin who uses smite evil on an antipaladin deals 2 points of damage per paladin level on his first successful attack.
