Cloak Of Shadows

Encounter, reaction; you cloak yourself in shadows. For a brief moment, you become one with the void, vanishing from sight and phasing beyond the ability of enemies to harm you. Roll a Dex save against one incoming attack or power; if you succeed, you become untargetable, avoiding it entirely. This can also be used against an active ongoing effect.

At rank 2, the cooldown changes to recharge 33%.
