Knowledge Fragments are an item that can be found as loot in chests found throughout the world. Although mostly useless early on, they have some uses later on, such as in Research and Infusion Enchantment. However, their only original use is to be converted into experience. Because of the aforementioned uses, though, this is not advised. They have no other uses than this, however, yet the few uses they do have are fairly important, especially Infusion Enchantment, allowing for powerful and useful enchantments.
