If you've been playing Baldur's Gate 3, you're likely to have missed out on a companion or two - as making certain decisions can affect who's available. Heavy spoilers for Baldur's Gate 3 are included in this article.
One of the most missable companions is Minthara, who appears in Act 1 of the game. In normal circumstances, recruiting her means siding with the goblins and attacking Emerald Grove along with the refugee Tieflings that are staying there.
However, this comes with some significant consequences - Halsin will refuse to help you later on in the game, and Karlach will be unavailable as a companion. Unless you're Taiwanese player pao870111, who came up with a way to recruit Minthara in a morally good playthrough without the use of mods.
