Corgi's Coal Overhaul Is a Mod that adds Coal Armor and tools, Dead wood type, Dead Biome and Superfuel! (also you can get the Dead Fruit item via creative)
The Dimension that is in the mod i cant tell you how to get inside of the dimension because of the curseforge rules. I will have a youtube video soon on my channel (corgiking54) about the mod.
This mod still has a few bugs and is about 98% complete.
If there are any issues with the mod please comment on the page.
Hope you enjoy!
