Attempt to finish off a wounded foe, causing X physical damage. Only usable on enemies that have less than 20% health.
Showing weakness to a Warrior is a death sentence.

Execute is a core warrior ability learned at level seven. It is an instant ability that can only be used when the target is below 20% health. The skill costs 30 rage to use.
Execute is a very powerful attack, but one that requires a bit of timing and practice. The base 30 Rage is unlikely to finish the remaining 20% of the target's health in one hit.
The emptying of the Rage Bar means that you will be left with no rage for the next fight. The introduction of [Victory Rush] has reduced this disadvantage, but it is recommended that you recast [Battle Shout] before using execute to finish off your opponent. This will allow you to attack your next target without having to waste rage to re-buff yourself.
Patch 3.2.0 (04-Aug-2009): This ability now never costs more than a total of 30 rage. The tooltip for Sudden Death has been revised to remove reference to that maximum, since the ability now behaves that way even when untalented.
Patch 1.3.0 (07-Mar-2005): Full rage is no longer consumed when the ability does not hit.
