Stalking Eye

This is an eye of the Old One (featured in Unicorn Rampant's Horror of the Old Ones), one that was severed or broke free from the body of the colossal god. The stalking eye is deaf, so it can be snuck up on, but has a supernatural sense of sight.

Combat

Stalking eyes will focus their otherworldly gaze on their prey, then close into melee with their claws and lightning touch, using their smaller eyes to affect their opponents and heal themselves.

Lightning Touch (Su): Stalking Eyes 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 21 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 (Su): 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 18 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.

The stalking eye also has a series of small eyes, each of which has its own ability per round, as it gazes at its foes:

Fear: works like the spell, but affects only a single creature.
Inflict Critical Wounds: (ranged, 30 ft.) inflicts 4d8+10 points of damage (Will half).
Cure Critical Wounds: heals 4d8+10 point of damage.
Slow: like the spell, but only affects one creature.
Dispel Magic: like the spell.
Fireball: like the spell.
