Lightless Deep
This Mod Adds A mining dimension called the Lightless Deep. In the dimension you can find powerful items and tools.
HOW TO ENTER
In order to enter the dimension you will require 10 Diamond Set Ametrine Blocks (more about how to obtain ametrine in the ores section) placed in the shape of a nether portal shape and ignited with a compressed emerald feather.

Ores

All ores added are found in the lightless deep, but ametrine can be also found in the end and compressed emerald can be crafted (as shown above) and all ores require at least a diamond pickaxe to mine (excluding Sandia ore). The two leftmost ores are ametrine, the one next to them is sandia followed by sapphire ore, Iridium ore is next to sapphire ore and adamantine ore is on the right of Iridium ore. The leftmost ore is compressed emerald.

Gear

All new gear (excluding sapphire and ametrine sets) can be crafted on a crafting table like diamond gear. Ametrine and sapphire sets are upgraded from iridium armour using the corresponding upgrade templates (found in the time capsule) and the correct material.
