Frequently asked questions

Why does the anvil say Too Expensive?

In Java Survival, a combination costing 40 levels or more is blocked. The limit applies to each operation, not the plan total. Having 100 levels does not remove it; renaming alone without repairs or enchantments is an exception.

How does the prior-work penalty grow?

A new item has a penalty of 0. Combining sets the new penalty to 2 × the larger input penalty + 1: 0, 1, 3, 7, 15, 31, 63. This reflects the depth of earlier combinations, not the total number of books used. Renaming alone does not increase it.

Should I combine every book into one first?

Not necessarily. Every transfer charges for the enchantments on the right-hand book, so both its contents and the two input penalties matter. The cheapest plan can mix individual books with small groups. The sum of level costs is not a number of XP points.

Can I reset the penalty and keep my enchantments?

A grindstone resets the penalty but removes ordinary enchantments and retains curses. Mending repairs durability with XP without increasing the penalty, but does not reset an existing one. If new enchantments exceed the limit, compare the same build on a fresh item.

Which item and book states does the calculation support?

The calculation uses Java 26.2 rules: one fresh book per selected enchantment, already at the desired level, with no prior work. The item can have a prior-work penalty. Material repairs, existing item enchantments, premade multi-enchantment books, and Bedrock are not modeled, so the displayed price is not an exact quote for those cases.
