Smoke Bomb

Smoke Bomb is a rogue PvP talent.

Tips and tactics
Smoke Bomb has a number of uses:
 * Protects party members within the cloud from ranged enemy attacks and reduces their damage taken by 20%.
 * Can be used to draw mobs that are reliant on ranged attacks.
 * Prevents enemies within the cloud from being healed (or otherwise affected) by their allies outside the cloud. As such, it can be used to great effect in PvP, providing a fairly reliable 5-second window in which healers outside the cloud will be unable to help those inside it.

While the Smoke Bomb prevents targeting into the cloud, it does not prevent AoE abilities from affecting those inside it. This is one way for distant healers (or attackers) to attempt to counteract the spell's effect.

Trivia

 * Smoke Bomb is one of Valeera's heroic abilities in Heroes of the Storm.
