Skeletons are definitely not a good indicator of a necromancer's strength! :( If you can build a magic amplifier and upgrade vampires in the game, then Necropolis becomes an unbeatable castle! For example, on the 3rd week, with Galtran and skills 9-9-4-2, with 24 vampires and 16 skeletons, I easily defeat Utopias on difficulty levels 1-2 without losing any vampires, and on difficulty levels 3-4, I lose about 5-6 vampires (and all the skeletons). Therefore, vampires are the most important offensive force of Necropolis! :) I, for example, don't even build dragons, but I build riders when it's most advantageous! :) This is my *tactic* for playing as a necromancer.
