Spell echo

Spell echo was an arcane spell of the illusion school of magic that revealed previous spells used within a given area.

Effects
The spell created an illusion that depicted the operation, or unleashing, of a previous spell, so long as it was cast within the once-encompassed area of effect of that spell. Multiple castings of the spell allowed a mage to sort through different spells cast in the same space, and it was possible to cast the spell to recall a given spell more than once.

The illusion wasn't devised by the caster, and so it was allowed as evidence in some legal proceedings. The spell only worked in Realmspace.

Components
The spell required only a somatic component.

History
The spell existed since the time of Myth Drannor, a fact known to Elminster. He had used it while he was hunted by the heirs of several houses in Cormanthor to taunt one of the hunters after destroying the sword they threw at him.
