Most Powerful BG1 Tutu solo character possible?

[Klorox]

I'm trying to legally, and under the 161,000 XP cap create the most powerful solo character possible without reloading.

The best I can think of is either any Dwarf (Berserker, Barbarian, a Fighter/Cleric or a Fighter/Thief) because they've got great saving throws, and will regenerate with a 20 CON. My other thought is a dual classed Berserker (for the immunities) 7/Mage. A Berserker/Mage can beat Drizzt and use the Defender Scimitar at the Grandmaster level. He'd have tons of HP and have Mage spells for protection. Another option I'm considering is a Berserker 7 > Druid. Druids can cast Ironskin... 'nuff said on an already formidable fighter. Problem is that rolling an optimal Berserker > Druid dual is really tough.
