Wizards can scribe any scroll to their spell book and learn it currently, Kryldost. This is not correct, and breaks several aspects of game balance. They are only supposed to be able to scribe spells that are on the Wizard spell list.
Seems like it would be super simple to implement. Reinforces that most folk at Larian have come into this unfamiliar with D&D. No D&D veteran would ever consider having wizards being able to freely cast cleric or druid spells.
