Illusionist

Illusionist is a passive ability, unlocked at character level 27.

Cooldowns of Archon variants of Teleport and Slow Time are not reset by Illusionist. There is no limit on how often the cooldowns can be reset.

Development
Before patch 2.0, the ability required the Wizard to take 15% or more damage in a single hit, making it useless against periodic damage. This was changed in 2.0.
