Tunnel Vision

This spell reduces the recipient creature's field of vision to the area that is directly in front of it, an arc 60° wide. All peripheral vision is replaced with a gray shading. Against attacks from outside this arc, the creature's Armor Class is reduced by 4, and saving throws are reduced by 2. The tunnel vision spell allows back-stabbing attacks from the side, and may increase the affected creature's chance of being surprised, depending on the situation.

Various cure spells cannot remove this effect; if the creature fails its initial saving throw vs. spell, then only a dispel magic or dispel illusion can remove the effect before the spell's expiration.
