Your best bet is to take the build which is posted and sub in skills you *do* have access to for ones which you don't trying to keep them as similar as possible. Farming builds are almost always a combination of skills from all campaigns for maximum efficiency. If you can't modify one like that you probably shouldn't even be farming really as you'll only get frustrated. generally speaking it'll likely be far more efficient for you to group farm though.
