Lacerates the enemy target, dealing X bleed damage and making them bleed for Y damage over 15 sec and causing a high amount of threat. Damage increased by attack power. This effect stacks up to 5 times on the same target.
This ability is used similar to a Warrior's [Sunder Armor], though it does not generate as much threat. However, Lacerate can crit, which increases the threat caused.
Tips and tactics
Very good skill for single target tanking. The tanking rotation generating the most threat is: Mangle (Bear) as often as possible; while Mangle is on cooldown, use Lacerate; if you still have excess rage, use [Maul] in parallel.
When tanking multiple mobs at once, Swipe is usually a better choice than Lacerate.
Past changes
Patch 2.4 introduced attack power scaling: Every 20ap adds 1 damage, per stack, over 15 seconds. Mangle further enhances this value.
