Vanilla Stoneblock

The mod is a datapack for the vanilla game rather than a set of new blocks or items. It adds a challenge that reshapes world generation and early progression, so only structures spawn in the world, and the vanilla Experimental Trading Features can be enabled for a faster route through the game. Witch huts are among the structures a player finds while progressing.

Progression is tuned around a few specific requirements. A sand, lava source block and lava are needed before the Nether can be reached, and the author notes that a Moss Block and a small set of items speed up the run. Because a bedrock roof blocks normal teleporting, the datapack keeps players from being moved down to the spawn point at 0, 64, 0. The design follows the spirit of the FTB modpack it is based on, but ships as a vanilla-based datapack.

The datapack is open source under the MIT License and is published for 1.20 – 1.21.4, with 1.2.8 for 1.21.4 as the latest file. Server owners install it on the server, and it is required there, while players can join with the vanilla client and no extra mod.
