“Flight to Salvation” – “Deeds and Paths of Darkness” [4th campaign, 1st mission]

At the beginning of the second mission, you'll find Hottabych and a lot of gold, which will allow you to level up into anything you want. The easiest way to complete the first mission is by using Armageddon and the new golems. It's also useful to leave Zehir with the "Master Summoning" skill and fire warriors, and learn the phoenix spell. There are also two witches on the map that you should visit, as well as an altar where you can exchange artifacts for experience.
