Hmm, I think I got confused. Chaos is more of an ultimate skill for Elves.
I found two bugs:
1) If Baal attacks Karlam after Karlam receives the Scepter, and it's not a mage who initiates the battle, then Karlam-Demon's army will consist not of Cave Lords, but of creatures from the Academy, which he will then use to fight against Baal. For obvious reasons, it's impossible to break through to the city in this case.
2) If Greta is in the castle garrison before the battle with Baal, the game will freeze when Karlam transforms into a demon.
Overall, the map is excellent. Also, a big plus for the built-in mod that increases the size of the text message window.
Thank you for the feedback. I will recheck the function that triggers the final quest.
