Coats your weapons with a Lethal Poison that lasts for 1 hour. Each strike has a 30% chance to poison the enemy, which instantly inflicts (2.8% of Attack power) Nature damage and reduces all healing received by 8% for 12 sec, stacking up to 3 times.
Wound Poison is a rogue ability that applies a poison to their weapons.
Every time the rogue hits with the weapon, there is a 30% chance to damage the victim and poison them for 12 seconds. The poison reduces all healing effects on the victim by 8%, stacking up to 3 times, or up to 5 times for Assassination rogues.
In PvP combat, the healing reduction effect is halved to 4% per stack.
