In Alchemy Classic, to create stromatolites, combine the elements of stone and life. First, ensure you have both elements in your inventory, then use the alchemy interface to merge them. This process reflects the natural formation of stromatolites, which are layered sedimentary structures formed by microbial activity. Once successfully combined, you will have created stromatolites in the game.
