This ancient spell allows caster to summon forth otherworldly doppleganger spirit entities that hover around him unseen to naked eye. As his opponents try to attack him the entities intervene and attack them back by the most horrific method possible; by turning into them and doing exactly what they were about to do split second ago. Having mirrors of some kind present seems to allow the doppleganger entities to work more efficiently for your cause.

This spell is related to elemental Magic.
