Discussion of third-tier monsters.

I voted for the vampires (I feel sorry for the poisonous creatures, but they don't stand a chance against the competition from the Necropolis) - probably the best creatures in the game in terms of price/quality ratio. In large numbers (and this is not a problem for a Necromancer's game), they recover from almost any damage, so without a specialized tactic against them, there's nothing you can do. Especially against neutrals. However, the Djinns, with their ability to disable and copy units, are also very good, allowing you to destroy huge armies without losses. And an army of Cyclops can wipe out troops more effectively than mass-effect magic.
