Level 60 build

I am doing a challenge where I try to beat all bosses in the game with my pvp character. My character is locked at level 60 with 12/5 upgrades. I will not be changing my level or upgrades because I want to keep invading with these stats.

My question is, what are some good builds for pve at this range?

So far, I have had luck with bloodhound fang, pulley crossbow, and flaming strike great katana.
