Victory Rush

Victory Rush is an instant attack causing a dynamic amount of damage that is based on your attack power (see in-game tooltip for exact value) and heals you for 20% of your maximum health. It can only be used within 20 seconds after you land the Killing Blow on an enemy that yields experience or honor.

The damage dealt is 56% of your total attack power.

Usability
Victory Rush can only be used if YOU get the Killing Blow on an enemy that would yield honor or experience (basically, an enemy whose level is not grey).

This ability can be used after scoring the killing blow off of snakes from a hunter's Snake Trap, so it is strongly recommended that you favor attacks such as cleave, whirlwind, and sweeping strikes while these snakes are on you, as every time you kill one you will be able to cast Victory Rush on the offending hunter (or any other enemy).

Suggested ability combinations
Because the damage done by this attack is based off of the warrior's attack power, any effect or ability that increases the warrior's attack power(AP) mixes well with this ability. Things such as strength potions, crusader enchant proc or strength/ap enchants, battle shout, rampage, Strength of Earth totem, mark/gift of the wild and trueshot aura, combined with talents such as rampage, improved battle shout and improved berserker stance can cause a warrior to do upwards of 2000 damage with this ability (assuming that the warrior causes a critical strike). It is not advised however that a warrior uses any ability with a long cooldown simply to increase the damage caused by their victory rush, as these abilities are better saved for more opportune times during a fight, instead of being blown right off the bat. One reason for this is that an enemy is very likely to polymorph you at the beginning of a fight to get into a better position, causing the majority of your attack power to do nothing.

Self-Healing
Victory Rush gives substantial self-healing, comparable to a Death Knight's Death Pact. The Glyph of Victory Rush will further improve this healing, as will the Field Dressing talent and any other talents or effects that improve healing done to you. (Note: Field Dressing does not consider Victory Rush self-healing for some reason, and will only improve the heal by 6%, not the additional 20%). This makes Victory Rush absolutely essential for soloing, as it allows a Warrior to kill large numbers of enemies one after the other, often completely regenerating his hit points in between each kill at higher levels. Not to be underestimated.

Please note that even if Victory Rush misses or is parried/dodged/blocked, you will still be healed.
