Sculk Depths
by warior456
Sculk Depths opens a dimension reached through the deep dark biome of ancient cities, with four new biomes, two structures, three mobs and a range of new blocks and items.
What it does
The mod adds a new dimension that players enter from the deep dark biome found in ancient cities, in the same way a portal leads to the Nether. Inside it, four new biomes and two new structures are generated, together with three new mobs. Sculk Depths requires Fabric API, which must be installed alongside it on Fabric and Quilt.
Sculk Depths is published for Fabric and Quilt across nine release versions covering 1.19.3 – 1.21.1, with the latest Fabric file made for 1.21.1 on the alpha channel. Versions 0.0.9 b and earlier also require Geckolib. The mod runs on the client and on the server, so both sides need it. Its custom license means the code is not open source, and the author notes that alpha builds may contain breaking changes, with changes kept as small as possible.
