So I had Shadowheart open the The Necromancy of Thay book. Place the amethyst in and pass all the wisdom checks. The book closes and now I have a new tag for Shadowheart as Evil Cleric. What does that mean and how will that affect gameplay?
You can get this tag if pick an evil god as cleric. For example I selected Selune and got good cleric options in dialogues and have some hilarious talks with Shadowheart)
