This mod adds Trialite Ore, which only spanws y=57 and y=4. They can be mined with an Iron Pickaxe or better. They drop Raw Trialite which can be smelted into a Trialite Ingot, like your typical Minecraft ore. You can craft it into a Trialite Block and you can use a Trialite block + 2 Copper Ingots in a vertical line to make a Trial Key.
To make a Heavy Core, you need to use this orientation of items:
Trial Key - Iron Block - Trial Key
Iron Block - Heavy Core - Iron Block
Trial Key - Iron Block - Trial Key
Use a mod like JEI to properly view the recipes!!
