In Baldur's Gate 3 if you want to respec your character, or respec origin characters or any other companions, there's only one guy who can do it for you. His name is Withers, and he's a spooky but friendly undead dude who will hang out at your camp providing respec services in exchange for gold.
Finding Withers isn't exactly easy, but it can be done very early on in Baldur's Gate 3, and it's well worth it to recruit him as soon as possible. As a bonus, Withers can also revive dead companions or provide hirelings for a fee.
