The golem is actually not too difficult to beat, with my party of lvl 10 Kia, Terry, and myself (courtesan, acolyte, and rogue) it was fairly easy fight. I basically just used distract on my courtesan to slow its actions and ramp up its lust to make it miss turns, while Kia buffed Terry and healed whoever the golem hit and Terry just dished out the damage.
