Active: Kha'Zix enters stealth for 1.25 second ignoring unit collision and gains Unseen Threat, gaining 40% movement speed. Kha'Zix can cast Void Assault again within 10 seconds after activation. There is a 2 second cooldown between each cast of Void Assault.
Evolved Adaptive Cloaking: While out of combat, Kha'Zix also passively gains Void Assault for 2.5 seconds in brush. This persists for up to 1.5 seconds after exiting the brush (10 second per brush cooldown).
