At the moment I from my Overview am at
Level 78
Dragons 118
Habitats 43/43
Farms 6/6
Evolution Temples 1/1
Breeding dens 1/1

Does anyone know the level markers where the amount of habitats you are allowed increases? Or is the number of habitats you are allowed determined by something else? Also does the number of Farms, Temples and Dens ever change?

Thanks for the advice in advance
