The Great Eye (CR 20)

A huge bulbous orb covered in rune carved chitinous plates with ten tentacles and a body covered in a multitude of eyes hovers menacingly before you. Where a mouth should be are jagged tusks and multiple gill flaps that open and close rhythmically as its singular central eye stares unblinking at you. As its four large tentacles writhe, its two smaller tentacles, each ending in three digit-like protrusions move with grace, gathering arcane energies that coalesce in a globe of flames about to be unleashed with devastating effect.

All-Seeing (Su) 

A great eye’s central eye allows it to see all things as they really are. The arcane eye is under the constant effect of an analyze dweomer, read magic, and true seeing spell. 

Aqueous Regeneration (Su) 

great eye gains regeneration 4 (healing 4 hit points per round) anytime it submerges itself completely within a body of natural salt water, fresh water, or brackish water. Stagnant, poisoned, or trapped water (such as water within an artificial pit or a bag of holding) does not activate this ability. Great eyes can heal up to 4 hit points per Hit Dice per day with this ability, after which it ceases to function. 

Electricity Healing (Su) 

Electricity damage heals a great eye 1 point of damage for every 3 points it would otherwise deal. If the amount would cause the great eye to exceed its full normal hit points, it gains any excess as temporary hit points-these temporary hit points last for 2 hours. 


great arcane eye casts spells as an 18th-level sorcerer.

Water Breathing (Ex) 

great eye breathes water and can use its spells and abilities underwater.
