Randomium is a simple mod that adds a new fun ore called Randomium
Note: Before you try anything smart you cannot duplicate anything that contains items and more specifically another randomium crystal. This includes stuff like shulker boxes, backbacks and other item inventories and prevents infinite duping. Most inventories from most mods are automatically detected and if they even were to slip away they can never be duplicated if they contain a randomium crystal since if they contain the word randomium:randomium anywhere in their nbt they are automatically blacklisted
You'll be able to find it pretty much everywhere in the overworld.
The mod is very configurable and you can do so via the provided configs and tags (through the use of a datapack)
Specifically randomium:blacklist disables all contained items from getting dropped & duped by randomium

Modding is taking a lot of my time, so if you like what I do, and you would like to support me, you can do so here. If you do, you'll receive a custom Globe and or Statue just for you! This also applies if you purchase a server from Akliz using "supplementaries" code.

A new ore that behaves randomly and can drop any item
