Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Reddit Repost: Karmic Dice and Armor Class

Also, fwiw, Karmic Dice was originally implemented by Larian because their base rng system was actually terrible. It made it more likely that low rolls would be followed by more low rolls (same for high rolls), making BG3 feel terrible to play.

However, since then they've fixed their base rng system...so there's no longer really a reason for Karmic Dice.
