Playing now a Fighter/Assassin through that marvelous EEKeeper mod, which also allowed me to change my PC appearence to that of a Thief instead of always looking like a fighter. My other favorite builds are Kensai/Thief human, Fighter/Thief elf and Fighter/Mage elf.

Never understood why Beamdog didn't implement being able to multi class into a kit if you start unkitted. As far as I know you can do that on the PnP and was a thing that players requested during development.

For BG3 I'm planning a Drow or Wood Elf sniper, most likely Assassin/Battlemaster which is the same as my tabletop character. I play a Drow, but it depends on how they'll be implemented in the game. Up to now there is no Dex bonus, as if Drow was not considered an Elf.
