OK, this is what you do. You make your Avatar (I used the Death Knight) and make him/her stay on your home tile. You then make a path from where the silver blocks end to your home tile, hopefully with Centaurs at first, so you have a lot of them. Do not get the treasures, they will only hurt you in passing this level. And as the level progresses, sell the hopefully many Centaurs for maybe Vampires, Liches, Elementals, and hopefully, Hydras. As long as you do that, you're going to win!
