Smoke Bomb

Smoke Bomb is a new rogue ability that comes with Cataclysm, learned at level 85. It was first announced in the Cataclysm rogue preview.

The rogue drops a Smoke Bomb, creating a cloud that interferes with enemy targeting. Enemies who are outside the cloud will find themselves unable to target units inside the cloud with single-target abilities. Enemies can move inside the cloud to attack, or they can use area-of-effect (AoE) abilities at any time to attack opponents in a cloud. In PvP, this will open up new dimensions of tactical positional gameplay, as the ability offers a variety of offensive and defensive uses. In PvE, Smoke Cloud can serve to shield your group from hostile ranged attacks, while also drawing enemies closer without the need to rely on conventional line-of-sight obstructions. Smoke Cloud lasts 5 seconds and has a 3-minute cooldown.
