Illusions





Illusions are imperfect copies of another unit. To enemies they look exactly the same as the original unit (with the exception of, , and ), but to allies the illusions are very distinct from the original one (illusions have a different color than the original unit, usually blue). Illusions run equally fast and attack almost as fast but their attacks usually deal much less damage and they usually take much more damage. With a few exceptions, illusions are controllable by whichever player they are created by. There are two types of illusion abilities: Mirror Image type and Single Target type. Illusions deal 25% less damage against buildings.

Mirror Image
Mirror Image type illusions are created at the caster's location and are mixed up with the hero so that enemies will not know which is which. These abilities also provide a short period of invulnerability and dispel most buffs and some disables. The following abilities are Mirror Image type:

Buffs illusions can use
Illusions can benefit from the buffs that modify heroes' intrinsic values, such as Base damage, Base Attack Time, attack range, base armor, attributes, health/mana, etc. If illusions are created when any of the buffs is placed on an Hero, illusions benefit from it for the buff duration (duration is refreshed for the illusions upon creation).
