An infused weapon with a prismatic enchant will work wonders for your DPS
I'll quote myself from various old posts :
"A PvP build and an IC PvE build aren't mutually exclusive. I solo farm the upstairs bosses with any of my PvP builds in about 5 minutes. A full PvE rotation could cut the time substantially, but is not required. The only thing harder are possibly the innermost walking bosses in the sewers. Everything else is a cakewalk, including the sewer bosses that are in fixed locations. Talking about full CP characters in CP campaign."
