Back slot question for lvl 56 Ranger

[Snaggles]

Any ranger soloing should have an earthshaker, tolan bracer, fleeting quiver, budget haste item (like SCHW's), and a bow that's 30dmg+.

Even with a kit like that, rotting a 6k hp npc is horrible. It's just *possible* and you will want that stuff anyways eventually.
