Walkthroughs for custom maps.

Since no one else responded, I'll ask kirill20148888: how should we conduct the battles you suggested? I watched, but I couldn't come up with a solution.

To avoid spoiling the fun for anyone, but to encourage those who want to try: all three tactical challenges are solvable. The author unintentionally left clues in the screenshots, in the form of a set of quickly applicable spells (left column).

I can add that I have already completed a battle similar to the third challenge, so I didn't repeat the feat, but I'm guessing it will take around 1000 attempts to find a solution. The first two can be completed in 15 and 5 minutes, respectively, if a tactic is found.
