Inferno tactics.

The army is weak, but for the tasks of the first week it might be okay; if you can break through to the grass at first, then it's absolutely wonderful. However, the respawn is quite poor, which isn't exactly good, and it's not a given that you'll manage to spawn above ground. This proud claim was made because there was an argument about taking the Dragon Utopia on the second week. And the external dwellings were not of Devils or Efreets, but of Imps and Demons.
