Ever wanted a dimension made out of diamond blocks? You can have it! With this mod for Minecraft 1.15.2 you can access the diamond dimension with only ten blocks of diamond, 1 diamond and 1 iron ingot!
This is how to access it:
You can make the diamond dimension portal just like you do with the nether portal, but instead of obsidian, you need to use diamond blocks, and instead of flint and steel, you need to use a diamond igniter, an item made with a diamond and an iron ingot in the crafting grid.
You need Minecraft Forge 1.15.2 to play this mod. When you download it, go to your .minecraft folder if you are experienced with installing mods (otherwise go to the Minecraft Wiki to see how to find the folder), enter the "mods" folder and place the mod .jar file there. The diamond dimension ID is 2005 so you don't have to care about the dimension clashing with dimensions from other mods.
