Boundless Ki (Su) An infernal creator is infused with personal energy. Its unarmed strike attacks gain a +5 enhancement bonus to attack and damage rolls. It also gains the AC bonus, improved evasion, and quivering palm abilities of a 20th-level monk, as well as a +4 dodge bonus to AC.

Omnipresent (Su) An infernal creator's blindsight and reach extend into all extradimensional spaces created by its own maze spell-like ability, regardless of distance. All creatures within these extradimensional spaces are within range of the infernal creator's blindsight and melee attacks, though the infernal creator doesn't otherwise have line of effect to these creatures.

Rain of Blows (Ex) An infernal creator can make dozens of sweeping unarmed strike attacks in a single action. Whenever an infernal creator makes an unarmed strike attack, it rolls normally but hits every enemy in its reach whose AC the attack roll exceeds. If such an attack roll results in a critical threat, the critical is applied to one creature hit of the infernal creator's choosing.

Stunning Slam (Ex) As a standard action, an infernal creator may make a single unarmed strike attack that deals normal damage. If it hits, the target takes damage and must succeed at a DC 41 Fortitude save to avoid being stunned for 1d6+1 rounds. Alternately, the infernal creator may choose to permanently blind or deafen the target. The save DC is Strength-based.
