All castles in Heroes 3.

Something like cloning, in the style of Necropolis or Inferno, but rather mediocre. I think the authors intended this to be the main idea. 1. Necropolis breeds skeletons. 2. Haven summons Archangels. 3. Sylvan domesticates Hives. 4. Inferno breeds strongmen. 5. Rampart crushes Mages. 6. Fortress (even with its low speed) brings early death with its overwhelming pressure. 7. Dungeon is extremely inventive, and therefore unpredictable. 8. Dungeon terrorizes with powerful magic. 9. And Conflux is simply overpowered.
