The bread and butter of the warrior. Launches 6 very fast strikes, for massive damage. Plus it seems that your target is unable to retaliate while the strikes are landing. The only downside is the 15 seconds cooldown. A point is a must, the more the merrier..
Is this really important enough to justify the extreme mana cost? (I'd rather not waste points on Mana Efficiency.)
Well, my warrior eventually was able to use it while only spending 3 points into Spirit and none in Mana Efficiency. It does a huge amount of damage, but if you use a lot of mana-using abilities, that might not be worth it.
