The main benefit of this attack is that you can swing uninterrupted, giving you the best chance to get your attack off, even in a crowd or against a faster foe. This one is actually a good deal at a cost of 2 Mana, especially if you have a good weapon.
Lore[]
Sometimes a series of blows is not nearly as effective as a single, concentrated strike. A Barbarian trained in this skill learns how to focus his strength into a single blow that cuts through the guard of an enemy and slices through their armor. This technique also puts the warrior in a superior defensive position.[1]
