Yokto Rustcell

The yokto rustcell replaced its ancestor, the lithocolony. Its most successful trait is that it no longer lives in colonies. The increased surface area allowed by that enables the rustcell to absorb more iron, giving it more energy to reproduce. It is now also more resistant to Mason's harsh climate, forming spores during the long night, or when there is not enough water to create the pools of damp mud it lives in. Much more successful than its ancestor, it has even replaced the mason rustcell in its biome.
