Minecraft wiki entry for Enchanting_Table, associated text: An item can be enchanted by using an enchanting table and placing the item in the input slots and 1–3 Lapis Lazuli in its dedicated Slot. Upon placing the item, three (pseudo)randomized options appear on the right of the GUI. The glyphs here do not affect the enchantment, but hovering over a presented enchantment shows one enchantment to be applied (on mobile devices, the player can tap an enchantment before putting in the Lapis Lazuli or hold the enchantment before release). The only choices available have a level requirement equal to or below the player's current level and a Lapis Lazuli requirement equal to or below the number of lapis lazuli placed in the table. Each option imbues the item with a randomized set of enchantments that are dependent on the number of experience levels required (e.g. a level 10 enchantment can give a pickaxe the "Efficiency II" enchantment); the actual level cost and the number of Lapis Lazuli required have no effect.
