In one playthrough I had SH dual-wield the Giant's club in her off hand, giving her Str15 and Booal sickle in her main hand. Had scalemail+1 for AC17.
Then I discovered they'd made Giant Str potions last all day (if you trade well, you can get 10-15 of them). I think she's proficient with hand axes so she got one of those instead of the club.
I cast Aid @ level 3 for +10hp for all. She can tank a bit if you gear her up and equip a shield.
That said, I've found her most effective being spec'ced for Wis & speed, casting Spirit guardians, and then a paladin casting Sanctuary on her. She ran around the goblin camp incinerating them where ever she went.
