So after using the Potion of Forgetting to respec and after unlocking Saia again I noticed that Damnation’s Edge is still unlocked and equipped to Saia even without the Trait unlocked. It didn’t revert back into its original artifact and it kept all its bonuses. I was not sure if this was intended or a bug.
