Turns you invisible over 3 sec, reducing threat each second. While invisible, you are untargetable by enemies. Lasts 20 sec. Taking any action cancels the effect.
Invisibility differs from stealth in that invisible units cannot be seen by enemies without special detection effects, regardless of proximity or level. However, AoE damage will still reveal invisible units.
Receiving beneficial effects such as healing or buffs will not break Invisibility.
Trivia[]
Invisibility is...
One of the Cleric's abilities in Warcraft: Orcs & Humans. Its description in the game manual reads: "This is the ability to cloud the perceptions of others so that they do not recognize the physical existence of the caster. This was originally employed as a tool to make the confessing of secrets that weighed heavily upon the souls of worshippers easier to speak. The clerics of Northshire Abbey have found it very useful in assisting the armies of King Llane in ridding Azeroth of the Orcs."
One of the Mage's abilities in Warcraft II. Its description in the Tides of Darkness manual reads: "Gleaned from sacred tomes rescued from the debris of Northshire Abbey, this spell grants the ability to cloud the perceptions of others so that they cannot perceive the physical existence of the caster's target. The individual that is rendered Invisible may not perform any tasks such as attacking, harvesting or spellcasting. Should the individual interact with his environment in any fashion more aggressive than simple movement, the Invisibility will be dispelled and their personage shall be revealed."
One of the Sorceress's abilities in Warcraft III. Its description in the Reign of Chaos manual reads: "This form of illusion has come back into widespread use since the days of the Second War. It creates a magical field around a person that does not impede the passing of light. Thus, normal people simply see directly through the invisible person. However, any attempts to attack or cast spells while invisible will cause the invisibility to dissipate."
A version of Invisibility existed in the original World of Warcraft beta, but was removed before launch.
