Access Arms (Su) Once per round as a free or immediate action, a fel'brute may call weaponry (as the power) to obtain a melee weapon as if spending power points to match the effective manifester level of this ability.
Brutal Heft (Ex) Once per minute, a fel'brute may apply its Strength modifier instead of its Dexterity modifier to one ranged attack roll using a thrown weapon. A creature hit and damaged by that attack is also dazed for 1 round (Fort negates) as a Strength-based effect.
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, a stunned or cowering fel'fiend is 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).
