Enraged Lunge

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

Usage

 * This skill counts itself as 'recharging' when calculating bonus damage. Using this without other Beast Mastery skills still gives the bonus damage x1. Ideally, only three other Beast Mastery skills are needed 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 with high enough beast mastery.
 * 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.
