I dug into this and every hallway has at least one if not more of these spots. I have a stack of diamond already without getting through half of this complex.
What pack?
What's REALLY going to bother you is that you didn't apply any lapis to that pick. You could have at 50% more if you mined it with a fortune pickaxe.
If you're lucky enough to get a really big mineshaft at diamond level, then it's normal. But you have to be pretty lucky to get that mineshaft complex.
Check your Thermal Expansion config for augmented vanilla worldgen settings (though depending on the version it might have migrated to CoFH Core).
diamond {
I:ClusterSize=10
I:MaxY=20
I:MinY=5
I:NumClusters=1
B:RetroGen=false
}
My CoFH World config said:diamond {
I:ClusterSize=7
I:MaxY=16
I:MinY=0
I:NumClusters=1
B:RetroGen=false
}
It's the New World modpacks which has super high diamond spawn rates. Getting a stack of diamonds is like getting a stack of coal in the other mod packs.
I don't often have trouble with diamonds, but as minecraft always is, the more desperate you get, the more impossible it gets to find.
when I need diamonds in the beginning I usually just start a 1x3 tunnel at layer 12 and continue till I find diamonds
