Seven-Sided Strike is a skill utilized by the Monk in Diablo III.
Introduced on the official website and in the trailer for the Monk, not much is currently known about the details of Seven-Sided Strike. When seen in gameplay, the Monk quickly rushes forward, and a large glyph of some sort appears below him. Up to 7 glowing apparations of the monk then attack enemies within the seal.
