Factions only Sin UW farm build?

I sadly only have factions, so i have limited sin skills, i was wondering if there was any builds that i could use that were factions only?

That's going to be tough. For one build you need Deadly Paradox from Nightfall and for the other you need some Prophecies only Fire magic skills. I'd go with another profession for UW farming until you can run the Perma-Shadow or the Shadow Nuker build.

P.S. For generic builds, visit www.pvxwiki.com. Good source for at least a framework for a build.
