I don't understand any magic at all. I choose everything at random. Well, intuitively. And I completed this mission on the n-th attempt, varying different sequences of actions. It's not a difficult mission at all and doesn't take much time, so it's not scary to fail it several times in a row. You won't get bored; eventually, you'll win...)))
For a Warlock, the most important magic is chaos. Here, as everywhere else, it is desirable to clear the stat boosters. I don't remember if there is anything here other than the arena. Archmages were guarding it for me. I cleared it at the very end.
