Brainstorm - Creature Mechanic - Creature production - Ideas needed!

[Sebt]

Our team agreed that creatures will be made from other creatures you find on the map - if you catch one, put in the Prison Room than throw into the Dark Mother's maw you'll get access to many creatures of caught creature's specie.

Actually this is the only method to make creatures that we set, but still we don't know exactly what will unlock more of them and for which cost and we haven't set any additional ways of making creatures - which many were proposed here by community. We also set that each creature you want to make requires some Evil Points to spend we discuss now, but opinions were differ.

Maybe something different could be better to unlock more creatures (remember that could that be creatures only of the same specie) thanks to have different things we make in the game - like in DK that was, however... in Dwelvers, each room that can be placed on the ground costs nothing to place - Room "floorings" are free to place, but Room Buildings not and maybe depending on number of specific Room Buildings or not number, but on whole Room efficiency, gathered points from this place or something - we could unlock new creatures.
