Anvil block in Minecraft

What it does

Put an item in the first slot and either its repair material (iron ingots for iron tools, for example) or a second item of the same kind in the second slot. Combining two enchanted items or an item and an enchanted book merges their enchantments. Every item remembers how often it has been worked on, so repeated repairs cost more and more levels; when the cost reaches 40 levels, the Anvil refuses with the message Too Expensive.

Renaming is cheap and works on any item. A renamed container shows its name in its interface, and a Name Tag has to get its name here before it works on a mob.

Each use has a small chance (12%) to damage the Anvil, which goes from Anvil to Chipped Anvil, then Damaged Anvil, then breaks. It falls like sand when nothing supports it and hurts whatever it lands on, more the farther it falls.
