Strange Looking Mirror

The strange looking mirror is a item dropped from the Shadow Player (100%). It will only drop one time for every player. If you kill the shadow player the second time, he will not drop the Mirror. If you use it, a message will say:

Monsters, created of pure Shadows are coming...

That means, Shadow Monsters will begin to spawn.

The shadow monsters are:
 * Shadow Skeleton
 * Shadow Zombie
 * Archer of Shadows
 * Dark Shadow (Miniboss)
 * They will only spawn in the night, on dark places.
