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 caster's receive a normal saving throw. The circle itself remains in place for 3 full turns, and creatures who 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 remains 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 a Dispel Enchantment, a Limited Wish, or a Wish can end its effects (remember that spells cast while deafened are 20 % likely to fail).
