Where it goes
Is Underneath required on the client, server, or both?

What else does Underneath-2.0.jar need?
Underneath-2.0.jar. Change the file and its required mods may change too.
Install Dregora RL, Scape and Run: Parasites, Dynamic Trees - Defiled Lands, Traverse Reforged and 13 more first, but 4 required mods have no matching file for this setup. Do not mix loader builds to force a match. 21 come through another mod in the chain.

What is Underneath?
Underneath is a dimension preset created using OTG for use with RLCraft & DregoraRL and exists as extension for the BRUH biomes. This dimension contains a higher amount of loot in comparison to the overworld but also is much, much more dangerous. Various traps within DregoraRL lead to this dimension and is mostly designed to escape from.
Underneath Consists of the following key points:
- A infinite procedurally generated cave system that consists of aproximately 5 different biomes.
- Uses SRParasites to populate said dimension and has Dregora's city structures generate within. - Hard to escape from, portal like structures at the bottom have to be lit with flint and steel to escape.
