It's similar to a pokemon nuzlocke
-Beat the campaign on hard/insane
-Once you lose a level or you resign you have to restart your progress
-mythics and enchantments aren't allowed
-if your general dies you have to restart the level, (this is the only time you are allowed to restart the level)
-items to choose in the campaign (there are a few levels that give you options)
-Thera
-Projectile barrier
-voltaic armor
-Pike
-Spirit Deads
-Barricade
(Noftify me if I'm missing anything)
