I tried that approach but she told me that she might not have time for me. Darkfyre doesn't **** for nobody. So I reloaded the save and betrayed her. Now she's all whiney and telling me that she doesn't want to see me again like a dumb child when I tell them on their birthday that their dancing is shit. If my kids can't take a few truth bombs from time to time then what's the point.On my moustache twirlingly evil cnut save, Shadowheart was just as evil as my character and had max approval where even Minthara was like "steady now" with some of the evil goings on.
If you go full evil with Shadowheart, she fully devotes to Shar, becomes a dark justiciar, eventually becomes leader of the Sharrans, murders her parents, murders Nightsong (daughter of Selune), defiles a shrine of Selune with Nightsong's blood and fecks you in front of it.
