Scripts

Hello everyone, I have a couple of questions: 1) How do I change a hero's specialization? 2) How do I remove the turn order panel? 3) There's a quest to defeat demons. This quest is executed through a script. The essence of the quest is to defeat two demon squads, i.e., one demon will be located in one place, and another demon in another place. After the demons are defeated, the task will be updated: you will need to return for the reward. How can I create a quest like this?
