Dirty_Player, I completely agree with what was said about dragons: I already mentioned that their magic immunity is a "double-edged sword," with the main drawback being the inability to resurrect or even heal them (unless with a tent and first aid skill). That's why, when playing as Fortress or Dungeon, there's a good reason to try to acquire the Sphere of Vulnerability. The second option: if there's enough strength to fight, I don't upgrade dragons when playing as Green or Red (but this results in a loss of initiative in battle due to slower speed).
