[Sir Heinrich Godfrie IV]

I am nearly finished with my current campaign, and am looking for ideas/opinions on a class that is both challenging, and fun to solo with. Logic would say, that a fighter/mage, a fighter/theif, or a fighter/cleric would be the most suitable. However, I want him to be pathetically weak in the beginning, yet still have the capacity to become one mean son of a gun! What I had in mind was a fighter/thief/cleric with the experience cap removed. He would progress slowly, but no slower (I think?) than a party of three single classers. The fighter side of him would take of the dirty work - Gibberlings and such, the thief side would handle the traps and locks, while the cleric side would perform the obvious healing and self-enhancements. I feel that there is a great potential for this sort of character, but since I have never tried soloing, I want your suggestions, preferrably through your own experiences. But any input is welcome.
