Spellstorm

When cast, this spell takes effect in a sphere centered on and mobile with the caster. It causes every normal physical weapon that comes within its area of effect to activate, tearing free of scabbards, bindings, hiding places, and chests to fly about at MV 15 (A), attacking the nearest living thing once per round with the caster's THAC0. For the purposes of this spell, normal physical weapons are all unenchanted objects that were made or carried thence with an intent to do harm to other living beings, or have been so used in the past.

While the spellstorm is in effect, unenchanted weapons cannot harm the caster-not even missile weapons launched from outside the area of effect. The spellstorm turns these weapons aside. The caster can ignore them, cast other spells, sleep, or stroll unconcernedly.

This spell is often used by the Seven Sisters to wreak havoc in a hostile castle, army encampment, or on a battlefield. Some use it to defend themselves by preparing a reception room in their towers hung with many weapons, and use the spell there.
