Baldur’s Gate 3 players have gotten really silly with mods since the game came out, including creating a number of mods that allow otherwise unplayable characters to join the party. But according to Larian Studios head Swen Vincke, a number of those characters may have been considered for inclusion as companions early in development, including one particular villain.
Sad but totally understandable why the Vlakkith parts were cut. I still wish the player could kick her ass, though!
