E/A Green Farmer

Ok, I recently made a E/A Green Farmer and am having success. I use guild wiki to see which bosses are doable and the difficult level. I have mostly been doing Easy ones and some Medium ones. Now I want to try hard but I think I shiuld have the right equips. Previously I was just using my Forgotten Staff. The only problem is wiki has two daggers, a staff, and/or a offhand/axe combo.

Am I supposed to have one of each, only one? and if it is only one which one would be the best?

Use a Ferverborn Staff and you'll be so wtfpwn it's not even funny.
