Skyblock Builder replaces the usual fixed starting platform with an island you design yourself. Build the layout you want, capture it with the vanilla structure block or with the mod’s own Structure Saver item, then point the configuration at that schematic and every new skyblock world begins on it.
The mod registers its own Skyblock world type, which shows up under More World Options when you create a world in the client. Servers switch over by setting the matching world type in server.properties or in the common config file, and because the mod is needed on both ends, it has to be installed on the client and the server alike.
Spawn points are part of the island definition, so you decide where players land instead of leaving it to chance. The mod requires the LibX library, and it is free to bundle, which makes it a practical base for anyone assembling a Minecraft 1.17.1 skyblock pack.
