For convenience, there are several stacks of Wyverns – you can choose a suitable terrain and divide the Wyverns into stacks – they are divided into either 4 or 5 stacks, depending on the cell.
WT version, morale is disabled.
Volland claims that he has 15 Air Elementals and 3 Foxes left. In my opinion, that's unrealistic. Maybe someone can tell us how this can be achieved.
