3. Tutorial: Loot Fabricator and Pristine Matter - CafeteriaGuild/DeepMobLearning-Refabricated GitHub Wiki
Now that you (hopefully) won a Trial and got its rewards, you may be wondering whats the use of those weird balls.
Loot Fabricator
Loot Fabricator is the machine you will be using to turn Pristine Matter into mob loot. It'll randomly generate loot from every mob in the its category.

Each Pristine Matter is equivalent of killing 16 mobs of its category. In other words the loot that will be given to you is what you would gain if you kill 16 mobs (with no Loot enchantment) of the matter's category. Technically speaking, the loot is dynamically generated by using the entitie's Loot Tables. You can input and extract items to/from the Loot Fabricator by using hoppers (or any pipe present your modpack).
