The creature tree of the necropolis town is a roller coaster of weak and strong units. The first-level unit, the skeleton is relatively powerful, and the upgraded skeleton warrior gains a much needed boost in speed. The walking dead and wights, however, are probably the weakest creatures of their respective levels. Even their upgrades are nearly useless, although you might want to keep a small stack of wraiths in your army to siphon away spell points from your enemies.
The unupgraded vampire is a weak creature in speed, damage, and other statistics. However, once you upgrade it, it becomes very powerful, especially in numbers. The ability to resurrect fallen creatures from its stack by siphoning hit points from enemies is a valuable ability. In fact, this resurrection ability is permanent and allows necropolis players to cause serious damage in conjunction with the power lich. You can send vampire lords into the enemy's midst, where the vampire lord can draw all the enemy opponents around it. Then the power lich can lob his corrosive cloud toward the vampire and harm only the adjacent enemy units, since undead are immune to the lich's splash damage attack. And if the vampire lords maintain their numbers by drawing life from the enemy by attacking and counterattacking, the strategy can continue. Cast a counterstrike spell on the vampire lord and they can last even longer, drawing life and resurrecting their numbers after each enemy attack. Large groups of vampire lords are practically invulnerable, except to ranged attacks and magic.
The lich is powerful, and the upgraded lich is even better, with more hit points and better speed. As mentioned above, the lich and vampire lord can work together for a lethal combo. But don't try it with regular vampires because without the resurrection ability, they fall too quickly for the strategy to work. The black knight is unequivocally the strongest sixth-level creature, and the extremely powerful, upgraded dread knight is almost as strong as the seventh-level hydra and behemoth. The bone dragon is a weak seventh-level unit, but the upgraded version, the ghost dragon, has a very useful skill: aging. While the ghost dragon is still weak relative to all other seventh-level creatures, its aging ability cuts the hit points of all the creatures in a target stack by half. A stack of 20 black dragons goes from 6000 hit points to 3000 hit points! A force of power liches, vampire lords, ghost dragons, and dread knights, backed by the magic from the necropolis mage guild is a powerful force to be reckoned with.
