Mordenkainen's Encompassing Vision

This spell grants a creature a full 360 degrees of vision, so the creature can see to the sides and rear as well as it sees to the front. The creature cannot be surprised from the rear by any attacker that the creature can see normally. The spell works in combination with any sort of enhanced or magical vision, including infravision, ultravision, or x-ray vision. A creature with both detect invisibility and encompassing vision can see invisible, ethereal, or astral beings to its flanks or rear as well. The person affected by this spell also has a -2 penalty on all saving throws vs. gaze attacks.

The material component is a crystal disc with eight eyes inscribed upon it, spaced at 45-degree intervals around the edge of the disc.

Notes: Uncommon or rare spell (WoG).
