Mantle of Mystra

Mantle of Mystra was a divine abjuration spell that created a protective aura around the caster.

Effects
When cast, the mantle protected the caster from a single, specific spell or spell-like effect. It absorbed the effects of the spell, or magical item discharge, then launched a single spell of the same power towards the caster of the offensive spell. The spell the caster was protected from, along with the spell that was "reflected" back, were both chosen by caster of mantle of Mystra.

The protection of the mantle lasted for a full year, until it was triggered by a spell's effects. Dispel magic didn't trigger the mantle's effects but effectively removed the protection it conferred.

Multiple castings of the spell could not be placed on the same individual at the same time, nor did they combine with the effects of greater mantle of Mystra.
