The Arcstrider is the new sub-class for the Hunter, and replaces the Blademaster. As an Arcstrider Hunter you'll be able to utilise an Arc staff, and when active, gain a polearm infused with Arc energy.

As you'll note below, the Arcstrider Hunter gains Grenades which provide greater AOE or single target pressure. In addition, their Jump can be dramatically improved to offer greater distances or a triple jump. Where the Arcstrider Hunters passive trees are concerned, they build on improving the sub-classes damage, or offering much greater sustain.
