Mantle of Mystra

(See also: Greater Mantle of Mystra) This spell creates an invisible magical aura around the caster. When a specific spell or magical item discharge (such as fireball, but not all fiery spells) impinges on any part of this aura, the mantle instantly absorbs it, negating all of its effects, and converts it to another specific type of spell, hurling that spell back at the source of the original magic.

This action exhausts the mantle, ending its protection. (It otherwise lasts for up to 1 year, even if its caster later memorizes other spells, but it cannot survive contact with a dispel magic spell. A given being can enjoy the protection of only one mantle of Mystra at a time.)

The returned spell behaves as if it were launched by a caster of the same level, alignment, and abilities as the caster of the first magic. Both the specific spell to be defended against and the spell it is to be converted to and sent back as must be chosen by the caster of the mantle of Mystra during its casting and cannot be altered thereafter. The magic defended against must be one the mantle-caster has cast, felt the effects of, or observed the effects of, and the specific name of the spell must be known. The return spell must be one the maw/e-caster has personally cast at some prior time.
