Don't use this weapon for dps, just don't even try.

Even with a god riven it sucks for that, just use a gun or a different weapon.

What it can do is heal reliably, so let's focus on that today.

The passive sucks orbs from corpses etc.

[Healing Return] heals on every impact proc because it has no duration, but only heals once for any number of slash procs, so staffs work great.

So; we get 100% status chance and just buff speed, additional status like corrosive and heat means additional heals. Use whatever status combo you want.

Buff the already good range to hit as many enemies as possible, and I think that about does it. Don't die out there.
