[Shattering Impact] and [Healing Return] are there because this is meant to pair with my shadow build, which uses arcane strike and [Fury] for extra damage and attack speed.

[Shattering Impact], is one of the best armor strips in the game, because it permanently drains armor from enemies, which means that your shadow can fully armor strip steel path acolytes in a few swings, [Healing Return] is one of my favorite HP [Regen] mods in the game because it scales with how many enemies you hit per swing as well, which is why prime [Reach] is there, and [Sevagoth] is great at bunching enemies up in front of him.
