Hello! Now, the mod in question might not be updated yet, I hope it is, I've gotten rather reliant on it. >.< In 1.10.2 when I look in JEI at an ore there is a tab that has the % chance of finding that ore at each Y level. You can poke at it and see that, say, iron is best to be found around Y 20, as an example. What mod does this and is it available for 1.12 yet?
