Mortal Strike

Mortal Strike is a warrior specialization ability, granted by choosing the Arms tree.

Mortal Strike is a significantly powerful attack in the Arms warrior's arsenal and is usually relied on as one of the top sources of DPS by this type of warrior; it delivers potent burst damage along with a significant debuff that reduces the effect of all healing abilities on that target by 10%, for the duration of the debuff (10 seconds).

 * Cruelty increases Mortal Strike's critical strike chance by 5/10%.

Mortal Strike with one- and two-handed weapons
Your Mortal Strike will deal more damage when used in conjunction with a Two-hander because it: a) gets a higher attack power damage bonus (modifier 3.3 instead of 2.4), and b) the base weapon damage is higher than the one of a comparable one-handed weapon.
