Walkthroughs for custom maps.

A hero with mages and hydras can be defeated with 400 harpies and blindness; you just need to find the right tactic.

I can give you a more precise hint if needed.

Although I messed up, I can attack him before the player and the Rampart appear, but I don't understand how to kill him with harpies. He kills them in 2 attacks, and their splash damage sometimes interferes.
