Help farming for Moo's wand

Hoy,

So to cut a very long story short, I made a plan to create five pirates and get them up to max level, with a witchdoctor as the initial pirate to go through and buy areas. Currently, im level 60 and just reached the mission after blowing up the turret. I've done every quest but am noticing that ive been having trouble hitting for good damage. And thats when it dawned on me: my wand is the problem.

I run Phules wand, and it carried me through a lot of fights. The witch hunter was surprisingly helpful in my first run of the tower of moo Manchu, but has begun to falter. Can someone help me farm moo for his wand? I know there was a sidequest that put you in a direct fight with him, but im past that.
