Enraged Lunge

Acquisition
Signet of Capture:
 * Royen Beastkeeper (Nahpui Quarter (Explorable))

Usage

 * What makes this skill most useful is that it counts itself as a 'recharging skill' when calculating its bonus damage. So even if you use it while no other Beast Mastery skills are recharging, you will still get the bonus damage x1. This means that, ideally, you only need three other Beast Mastery skills to be recharging in order to get the max +80 damage bonus if your Beast Mastery is at least at level 13.
 * Tiger's Fury disables all non-attack skills for 5 seconds, including Charm Animal and Comfort Animal (disabling counts as recharging). So, the full +80 dmg is achieved with the disabling of Charm Animal and Comfort Animal, the recharge of Tiger's Fury, and Enraged Lunge itself.
 * This skill is very useful in the R/any Tank Master build. By keeping a constant stream of recharging Beast Mastery skills, the tankmaster can repeatedly deal tremendous damage.
 * The amount of damage that a pet can do with this skill also makes it ideal when attempting to evolve a new pet into a dire pet.
