Many players argue about which units are better to defend the fortress, the occult units or the bestiary.  For example, in a tournament, the prize was 400 golden dragons, but 400 dragons equals about 2950 demons.  And the defense rate of 2950 demons is higher than that of 400 golden dragons. Where will the losses be greater, in the occult or the bestiary? Which kind of troops are the best choice for the fortress, i.e. minimum losses, golden dragons or demons?
