Execute



Execute is a level 10 warrior ability. Execute can only be used when the target is below 20% health. For Arms and Protection, Execute has no cooldown (except for the global cooldown), its base Rage cost is 20, but it can consume up to 20 extra to deal more damage. For Fury, Execute has a short cooldown and doesn't cost anything, generating 20 Rage instead.

Tips and tactics
When an enemy with a lot of health such as a heroic or raid boss gets below 20% health, both Fury and Arms warriors should change their rotation to spamming Execute. However it is worth refreshing Colossus Smash on the target whenever possible.

For either spec, judicious use of Berserker Rage can increase output during an Execute phase. The more rage available for Execute, the better.
