So I'm clear, I need to take two classes and not a "split" class, right? Like I start out as a fighter and then multi over to thief at some point. Or is it the other way around? Any build details you can give me, or even a link to some elsewhere would be awesome. I might start the char out in BG1 and go all the way through, though that might make it more complicated since I'm not sure how balanced/what kind of gear there is for a F/T in BG1. Thanks for the help.
Well, my example was a multi-class. You start both classes at the same time. A dual-class character starts one class and then switches to another one (can't progress in the first one ever again).
Starting as a fighter and then changing to thief -> dual-class
Starting as a fighter and thief together -> multi-class
A dual-class earns EXP in one class only (either the one pre- or post- going dual). A multi-class gets EXP the whole time for both (or three) classes equally, but it's split evenly (so gaining 1000 EXP gives 500 to fighter and 500 to thief). BG1 has proper gear for a multi-class. Especially if you manage to kill Drizzt
As for tips? Roll as many times as you need to get CON to 18, DEX to 16+, STR to 18/xx as high as you can (don't remember if multi got 18/xx or only 18). You can find special books in BG1 that grant +1 to stats permanently, so those 18s will turn to 19s

The rest can be 10-ish. Since you're playing BWP, there's no EXP cap in BG1, hence you shouldn't worry at all (vanilla BG1 had 89k / 115k caps). Though your character will be insanely powerful at the end of BG1 (Sarevok won't stand a chance). There are plenty of guides, but really... There's not much to playing a class. Just think a bit (you won't be running in a robe as a fighter for example

). One detail - to use thief skills as a F/T, you can't wear anything better than studded leather armor (or elven chain mails). However, there's a nice +3 Studded Leather armor available in Beregost

Can't remember the name. You got boots of stealth nearby too (for free!). Also, you can't backstab with bastard swords and two-handers, obviously. But you can use any weapon the fighter can use. Backstab is only available when using thief-available weapons and thief skills are usable only when in thief allowed armor. Hence why a F/T/M is so hard at the beginning - you can't wear any armor (or no spell casting), can't use heavy weapons (or no backstabbing) and with those defenses you die fast in first row

Later when you get protection spells, good robes etc, it is great though.
The rest you'll find out as you play
