Warlock – “Expansion” [4th campaign, 2nd mission]

To ensure you have enough mana, you definitely need to increase magic affinity. It's best to get Secret Knowledge and Mutable Mana. Without Arcane Wave and increased mana affinity on the hero, it will be very difficult to complete the next mission. In version 3.0, I couldn't even complete it – I'm playing on Veteran difficulty. In 1.5, I completed it easily, but in 3.0, it's something terrible. At the same time, it's desirable to get Sorceress's Luck for Railaga as quickly as possible, at least by level 25. Shadia won't need it anymore. You will probably have to visit Shadia's Utopia and Treasury more than once. In addition to Magic Defense, both heroes will need Earth Shock. If it's not available in the castles, you need to obtain it from mages and dragons.
