Allows you to vanish from sight, entering stealth while in combat. For the first 3 sec after vanishing, damage and harmful effects received will not break stealth. Also breaks movement impairing effects.
Vanish is a level 32 rogue ability allows a rogue to disappear from sight, entering an improved stealth mode for 3 seconds even while in combat. During that time damage and harmful effects will not break stealth, but they will still afflict the rogue. Once the Vanish buff has worn off, the rogue will still be in standard [Stealth]. Upon being cast, Vanish also breaks any movement impairing effects. In addition to escaping, Vanish can be used as a damage cooldown, especially when the [Subterfuge] talent is chosen, as well as a powerful PvP cooldown allowing the rogue to briefly "pause" combat and then repeat an opening attack sequence.
Vanish and [Sprint] away when you are outmatched or need to recover, or when you pull a mob you don't want to attack right now.
In groups, use Vanish if you are approaching the tank in threat, or have already drawn aggro. Keep in mind that if you Vanish while having aggro the mob will attack another party member; try to make sure that person isn't a healer.
Ostensibly a defensive ability, Vanish also enables you to use your opening attacks ([Ambush], [Cheap Shot]) multiple times during a fight.
When stealthing past high level mobs or moving in for a [Sap], utilize Vanish's improved stealth to ensure the enemy doesn't see you.
