This mod is including nearly everything in the world. There is a diamond furnace but it won't work in this version. I'll try to make it work in the next version in 1.2.0. I decided to add an overlay. It says '1.12.2 Forge' I think. The other one says the block is located at 100 100 and 100. That is where the structure of the reward block will be. I still didn't add it but I might change the structure into an improved dungeon. Don't get too excited because it might be added in the 2.0.0 update. It will happen next year. There is a chance I won't add it. There is magic dust that can be used to make a beacon in a cheaper way. To get that you need to go underground and you need to find a blue, transparent ore. You can make a multitool with it in the next update. It is already released. See more in the next update. It will be in the next month.
