Demon invasion.

Special spells shouldn't be nerfed; they are helpful at the beginning when it's difficult and you need to level up, and later they become less relevant or not very relevant. Changing the "Devil's Strike" ability will significantly affect the second part of the campaign, where the war against the dwarves is led not by Sigrif, but by Grol or another firstborn demon. In that same second part of the campaign, to successfully complete his part, Sigrif needs to choose an artifact, and this artifact must definitely grant spellcasting; otherwise, even on a warrior, winning a battle against a necromancer, as well as defeating neutral creatures, will be very difficult. Or should we release two versions – one with nerfed spells, and the other without?
