I'm not sure if demons will come to me in the 3rd mission of the campaign for Railag. But there, it seems, it's not necessary to kill them. Otherwise, everything works fine. The walkthrough differs from the walkthrough in version 1.5 because you need to level up the heroes differently. I especially managed to create a level 30 Agrael. SA, speed aura, and a full set of dark magic spells allowed me to complete the entire fifth mission without losses. In 3.0, in the 2nd campaign, the guild lacks the ability to summon a ship. Therefore, I had to defeat 72 emerald dragons. And sometimes the AI behaves unusually.
