Another party option is a Warrior hero, two Dark Lords (I rarely go with skeletons, even though they are stronger, but it takes a long time to level them up, and they also have poor elemental resistance), a couple of Shadows (one misses too often), and a Vampire (you can also use a Lich, but I like healers).
