|Poor Wandering One|
I am looking for a fun, effective built, not necessarily the absolute best possible build.
I had a gnome hook-hammer specialist a while ago who fit your fun and effective criteria. The basic skeleton would work fine as a staff fighter.
Lvl 1: Vivisectionist/Internal alchemist.
Reasoning: The sneak attack will help support the meh staff damage. You also get a small spell list and some nifty tricks for when hitting-them-with-a-stick does not seem the best choice.
Lvl 2 and onward: Ranger.
Reasoning: Two weapon fighting feats, full bab, built in flank partner even if none of the other players are willing/able to dance.
Worked surprisingly well. Not overly specialized so not the best power-build but it was fun to play and added a good bit to the party.
