About this Mod
Sculk Depths
project is on hold for an unknown amount of time, we lack the manpower (artists and experienced modders) to complete this project to our vision, if you think you share our vision join the discord and ask

Important Notes
- versions 0.0.9_b and earlier require Geckolib
- Quilt has been found to work with the right combination of fabric api and quilt loader but is not (yet) officialy supported
- This mod is in alpha, we keep ourselves the right to make breaking changes (we will try to minimize damage where possible)
- The 1.20 release no longer supports worlds created with older versions. The file "biome3.json" has been removed, causing biome3 to revert to plains. This change does not affect the 1.19 releases, where this biome will continue to be supported (for now).
ABOUT
This mod adds a new dimension called "Sculk Depths" to Minecraft.
To access this dimension, follow these steps:
- Search for a deep dark biome with an ancient city.
- Summon a Warden and let it kill a passive mob like a cow, sheep, or horse OR kill the warden.
- this will drop Energy Essence which is used to craft an Energized Flint and Steel
- Clear all the sculk veins from the middle of the reinforced deepslate in the center of the city.
- Use the Energized Flint and Steel to light the portal.
When entering this dimension, it is recommended to bring a netherite pickaxe because the planet is mostly made of a very hard block called Umbrusk.
