I'm working on a solo MP Sorcerer build. I've taken the base from one of Marty4's post and tweaked to fit my own needs. I figure 24 Sorcerer levels will get me the spells I need while allowing me to mix in 6 levels of other classes. Since my character is going to be Drow, I'm thinking of mixing in Rogue, Ranger and Barbarian. This is what I've got so far:

Kreios Chaotic Evil Male Drow
Rogue 2/Ranger 2/Barbarian 2/Sorcerer 24
STR 14 DEX 18 CON 14 INT 8 WIS 6 CHA 20
Dual swords, Bows & Maces

However, I am considering dumping 2 STR into CON and taking Weapon Finesse. Other than the change in weight limit, is there anything else that would be effected negatively for doing this? Also, what kind of xp penalty am I looking to incur? I know xp penalty will be based upon the way I level up. So far, I'm thinking of leveling up like so:

Rogue 1, Ranger 1, Sorcerer 4, Barbarain 2, Sorcerer 6, Ranger 2, Rogue 2, Sorcerer 24

I'll probably take the first 2 Sorcerer, squat the next two and then squat the 2 Barbarian levels. Anyway, that's kind of the plan I have for now. Thoughts and suggestions are welcomed.

Thanks,
