It's indeed strange what you've with Rothman .... can it be you said something to him that break the option to free him ?
but if you like to use a bow, take the one of Hermit (Mister Shooty L16 with Ranger Stealth +1 on it) ... you can pay with Spoons ...
For me a melee character is more difficult to play with because the melee battles are to fast for me ...
I discovered ca. a year ago that a Priest build suits me best.
Charm, Blind, Fear, Curse, Summon Ghost(!), etc ... love them all !!
For my Priest build a Creature with a Ghoulish Head (Fataltiy & Rush Attack) I like most and comes in handy to attract enemies so I can Charm, Blind or Curse them ... or whatever I like (using Polymorhp, Thousand Strikes, ... via skill boosts on yewellery) .
