Throws your weapon at the enemy causing X damage, reducing the armor on the target by 20% for 10 sec or removing any invulnerabilities.
Shattering Throw is a core warrior ability learned at level 74. It is a ranged attack that debuffs the enemy target with reduced armor or removes any existing invulnerabilities.
Also, a warrior can use it on a high-armored target to attempt to increase the damage it takes, an example is a boss during a high-DPS phase, such as during Bloodlust or Heroism.
