To build, you need four obsidian, two diamonds, and a book. To assemble it, the book must be in the top row, the diamonds must be on both sides of the middle row, with obsidian in the center, and on the bottom row. To use it, you need experience points, which are now numerically-tracked in version 1.9pre4 and above. For every full experience bar, you will receive one point. To use it, set any tool, armor or weapon in the enchantment table slot and blindly pick an upgrade from the list of those available. Every time an item is placed, the available upgrades change. To further confuse players, the upgrade selection is presented in a cryptic, foreign language. Even if translated, the translation would not correlate with the upgrade. Thus, all enchantments are still fairly blind even if the words for them were translated. An enchanted item will have an indigo glow around it, and usually has some special property, for example: fall protection for boots, fire from sword strikes, and respiration with the helmet when underwater. An enchantment table is capable of more powerful (and expensive) enchantments when surrounded by bookshelves, which must be in the adjacent area. Ideally, bookshelves outside a 3x3 square, with the table in the middle, is more capable of enchantment than a table in the middle of an empty field.
