Barbarian half-orc, Drow or halfling Gloom Staker, Some type of Pact of the Blade warlock... Maybe Paladin Dragonborn, I considered a bard, too. I dunno. Frankly the more I think about it the less confident I become.
The final choice will depend a lot on how I like the result in the character creator, probably.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
