Juicy extra Shadowheart content originally sliced out of the Baldur’s Gate 3 full release has now been restored by fans, with the “DLC” add-ons (which mostly revolve around her deity Shar) adding more dialogue options for the fan-favorite companion.
Baldur’s Gate 3 modder OddCoward was the one who has now restored the originally-cut Shadowheart extras and her deity Shar’s content. The mod pack, Shar Deity (with restored cut dialogue), gives you the choice to pick Shar as a deity and learn more about the religion—which, in turn, gives you more dialogue pathways.
