This spell wards the creature against a single spell or spell-like ability that directly affects it. A fireball flames around the warded creature without damaging it, and an acid arrow fizzles uselessly, but an earthquake still damages the recipient (although it can still face a finger of doom next round without fear).
Any spell that allows spell resistance is nullified with regards to the recipient of this spell. Any other effects of the spell still occur. For example, a sunburst will still damage and blind others, and multiple magic missiles can be fired at both the recipient and other creatures, damaging the others normally.
The recipient cannot choose to accept a spell that allows resistance. A fly spell, for example, will discharge the scatterspell, rendering it useless.
Material component: A ring made up of the woven hair of a creature with natural spell resistance. It must be worn by the target until the spell discharges. The spell ends early if the ring is removed or destroyed.
