Begotten warrior

This twisted monstrosity, when warped by the Old One's otherworldly energies, retained a sliver of it's mind where it's martial skills were. Now it lurches about in it's deformed plate armor at the beck and call of it's master, the Begotten Wizard. On twisted limbs, encumbered by the heavy mail permanently fused to it's wet hide, this horror lurches indomitably forward, it's tentacle-like arms wrapped around the haft of an enormous flail, the head of which is encrusted with dried bits of hair, skin and bone.

The result of prolonged exposure to Old Ones, persons too near their reality warping effects undergo a transformation into beings which resemble them in some ways. These changed creature's features are bestial and reminiscent of fish, lizards, and amphibians, with claw-tipped hands or occasionally tentacles for arms. They are cunning and physically powerful, yet twisted and crippled in appearance. These creatures are ruled by the Old Ones through fear, violence and mental domination.

Those that can still speak do not usually chose to do so. Instead they mainly communicate simple thoughts to each other by telepathy, accompanied by whimpering groans and croaks.

Lightning Touch (Su): Begotten of the old ones can generate, as a free action, a burst of electricity from within their bodies that damages and may stun their victims. The touch deals 1d8 points of electricity damage and stuns the target for 1d4 rounds. A DC 17 Fortitude save avoids the stun effect - the save is constitution based. They may use this ability once per round, delivered by melee attack.

Otherworldly Gaze: As a standard action begotten can focus their otherworldly gaze upon a mortal creature and create a haze of confusion as the spell. A DC 17 will save is required to avoid this confusion (save is wisdom based), which lasts as long as the begotten concentrates upon it. This is a mind-affecting ability.

Spell-like abilities: blur 1/day. Caster level 5th.
Damage Reduction: 5 / lawful (axiomatic)

Tactics
This horror will charge it's enemies without heed of harm to itself. Those that harm it may have their weapons smashed by the being's heavy flail via improved sunder, or it may smash the shields of those it cannot harm in the same fashion.
