Mass Blindness

This spell strikes blind or deaf, or both, all creatures up to 4 Hit Dice with no saving throw. Those of greater level or Hit Dice, but less than the caster save vs. spell at -4 to avoid the effect. Creatures whose levels or Hit Dice are equal to or greater than the casters are receive a normal saving throw. The caster can designate one specific group to be excluded from the circle's power; for example, the spell could blind all but humans, all but wizards, all but royal guardsmen, and so. The circle itself remains in place for 3 full turns, and creatures that enter the area of effect during this time are also struck by the spell's effects. Magical items that enhance sight or hearing are rendered inert.

Affected creatures and magical items remain affected until the spell ends or they blunder out of the area of effect. The effect cannot be ended by a dispel magic spell, but dispel enchantment, limited wish, or wish can end the spell, and an antimagic shell suppresses its effects (remember that spells cast while deafened are 20% likely to fail). The caster can end the effect at will.

Notes: Uncommon for illusionists, necromancers, and shadow mages; very rare for others.
