SPECIAL ABILITIES
Concealed Alignment (Ex) Fel'fiends radiate no alignment aura. This affects only alignment detection, not effects that cause harm or are otherwise based on alignment.
Cosmic Defiance (Ex) When and wherever it is advantageous for them, stunned or cowering fel'fiends are only considered dazed.
Cosmic Strike (Su) The natural weapons of fel'fiends, as well as any weapons they wield, are considered ghost touch seaborne weapons and overcome all forms of damage reduction based on magic, alignment or material.
Cosmic Tolerance (Su) Fel'fiends adapt to hostile environments as per adapt body (psionic power).
Fel'fire Blastwave (Su) Once per minute as a free or immediate action, a fel'pyrolith may erupt in an instantaneous self-centered radial burst of fel'fire extending any distance it desires out to close range (25 ft. + 5 ft./2 levels). In doing so, a large creature deals a 2d6 base amount of fel'fire damage to other creatures and unattended objects in the area (Reflex negates) as a Constitution-based effect. Any creature using this ability applies their Charisma modifier and total Hit Dice to such damage. While not subject to resistance or immunity, fel'fire damage is considered fire damage. This is a supernatural evocation [evil, fire] effect that functions normally underwater and deals damage normally to incorporeal targets, but cannot start or spread fires.
Fel'fire Corona (Su) As a free or immediate action, a fel'pyrolith may suspend or resume the green flames that burn harmlessly around it with the brightness of a torch. A large subject of this effect can add a 1d8 base amount of extra fel'fire damage to any melee damage roll it makes. A subject of this effect applies their Charisma modifier to such damage. Damage dealt by this effect is not multiplied in the event of a critical hit. While not subject to resistance or immunity, fel'fire damage is considered fire damage. This is a supernatural evocation [evil, fire] effect that functions normally underwater and deals damage normally to incorporeal targets, but cannot start or spread fires.
