How about a spike chain fighter. A elven spike chain fighter 2nd lv, Swash buckler 3rd lv. Give it stats like Str 14 Dex 16 Con 12 int 16 wis 9 chr 8
feats, exotic weapon profs spike chain, combat expertise, improved trip, power attack, weapon finesse (spikechain) free with swashbuckler class.
So you have a attack with mastercrafted spike chain of +10 dam 2d4+6 damage, and if you power full at +5 you now have a +16 damage. (str 1 1/2 for two handed, and int +3 added for insightful strike of the swashbuckler. now you can up the damage with getting guantlets of orge power or perhaps put a flaming or frost on your spike chain. )
Needless to say that your initial attack is down as a trip (touch attack and can power in it.) That you get a automatic attack if win trip.
Just a suggestion.
