I'm trying to use this build, and it seems to be working fine so far (I haven't 'soloed' anything yet because my dervish is only level 18). Can this build also be used to solo the UW? The main reason I want to know this is because I like the FoW armor, which requires a lot of ecto obviously =p.
Any other tips on how to refine this build to make it better would be great.
