|A hand mirror which can create a reflection of a nearby creature, shattering in the process. The reflection's duration increases with Evocations skill and decreases with the magic resistance of the target. It is, invariably, slightly weaker than the creature it mirrors.|
Evoking a phantom mirror allows you to summon into existence an exact duplicate of a single non-player, non-magic-immune target. It is a one-use item, and will be destroyed upon a successful use. The chance of it succeeding, as well as the duration of the summon, is dependent upon your Evocations skill and the target's magic resistance; high MR targets are much more difficult to duplicate, and magic-immune targets simply cannot be affected.
Phantom mirrors will be added in 0.16.
