About Skyblock Builder
From ModrinthLet you create a custom skyblock island via config
Porting information for 26.1 update 
This mod allows you to create custom skyblock islands via config.
You simply create a schematic file using the structure block from vanilla Minecraft, or the Structure Saver item and set possible spawn points for the island.
This mod is required on server and client side. It adds a "Skyblock" world type at "More World Options..." setting when creating a new world on client side.
For servers, use skyblockbuilder:custom_skyblock (1.18+: skyblockbuilder:skyblock) as world type in server.properties or in forge-common.toml (config, was removed in 1.19).
This mod requires LibX.
