The best all around strategy I’ve found (stolen from these forums, actually ;-)) is to only hit the little creeps at night. It reduces the chances of a poison arrow, and once you get close enough, even a low level brother can do pretty well. If they nerf the rotten scumbags, it would be too easy to just steamroll them. Especially when you finally do get brothers like Sarissofoi has! ;-)
In a single player game, there's no such thing as cheating. It's merely "creative manipulation of the default settings"!
