About Sulfur Caves Backport
From ModrinthBackports the Sulfur Caves from the Chaos Cubed (26.2) game drop. Does NOT backport the Sulfur Cubes.
SULFER CAVES BACKPORT MOD
Backports the Sulfur Caves to older versions of MC, in a kinda shitty fasion.
Currently on Snapshot 3
Sulfur Caves spawn similar to how they're stated to spawn on the wiki, though a bit rarer. Mob rates are 1:1 with the wiki outside of Sulfur Cubes, and Cinnabar / Sulfur distribution aint 1:1 but similar.
Includes all the cool new sounds! Very satisfying.
