Victory Rush is a level 10 warrior ability. It is an instant attack that deals damage and heals for 30% of maximum health. It can only be used within 20 seconds after landing a Killing Blow on an enemy that yields experience or [Honor].
Because this attack deals damage based on the warrior's attack power, any effect or ability that increases the warrior's attack power (AP) mixes well with this ability.
The self-heal makes Victory Rush absolutely essential for soloing, as it allows the warrior to kill large numbers of enemies one after the other, often completely regenerating their hit points in between each kill at higher levels. Not to be underestimated.
Note that even if Victory Rush misses or is parried/dodged/blocked, you will still be healed.
