Same here id be nice to have a guide on this

So I actually have a question to how would I make my biome only spawning in my custom dimension and not the overworld

You need to make a Biome for your dimension or you can use a vanilla biome but if you want to customize it then you would need to make a BiomeGenModname file

So I'm still entirely confused on this how would you go about adding the effects to the armour?
