Skyblock - Infinite is a very simple, but powerful, extension of the typical skyblock experience, founded by Noobcrew and adopted by millions. This Skyblock map, while not a modification of the original, is an adaptation of it. It is the same skyblock everyone knows and loves, but with addition of a villager that trades for items that could not normally be obtained in skyblock. This map is simple, it's just you, your island, and a floating villager. It allows you to obtain new resources as well as materials that allow you to reach the nether and the end. So now skyblock is beatable the same way vanilla worlds are. Additionally you can spawn in passive mobs, a feature that spawn mechanics have halted since the original skyblock, many Minecraft versions ago.

Keep in mind that the villager floats in the sky for Java Edition, but due to limitations, in the Bedrock edition the villager stands in bedrock.

Skyblock - Infinite is available with Java versions 1.14 up and Bedrock versions 1.11 and up. If it stops working in a future version I will indicate that here.
The Java version can be downloaded above and the Bedrock version should be downloadable from MCPEDL in the coming day or so, I will put the link here when that happens.
