This idea is for all those that don't want to have to mine all those blocks to make their island down to only the bedrock so they can make awesome patterns and structures without an island they have to either break down or cover up. The 1*1 island would be a bedrock and a dirt with a tree on top and the player would spawn on top of the tree with the chest. If this is too small do something where it is a 3*3 with the bedrock in the center and a 3*3 island of dirt on top with the tree and chest on it. This idea is simply to recommend a small island that is easy to remove so players can start their designs sooner, especially if they have ranks and or fly. However this idea is also nice for players who want to go really hardcore with their skyblock experience.
