I'm currently reviewing the hero lists and balancing them.
It's annoying that so many heroes in the game are duplicates of each other in terms of specializations (for example, Nimue and Biara, Wier and Marbas, etc.).
By the way, regarding Biara - she is known for her ability to create illusions and weave intrigues - we can base her specialization on this. For now, I have an idea to take the "Dancing in Twilight" specialization and the "Create Phantom" spell and develop it like this:
Master of Illusions: "The hero is able to create illusions during battle, making it more difficult for enemy creatures to target and reducing the damage they inflict with ranged attacks. The hero starts the game with the "Create Phantom" spell."
I agree with this. I especially liked the idea of a master of illusions.
But I wouldn't want you to delay the release of the mod too much, as interest fades over time. I hope you understand.
