Minecraft anvil Too Expensive: diagnose the blocked step

Read the message before changing the item

For the book combinations modeled here, Java 26.3 Survival rejects a step that costs 40 or more experience levels. Having 100 levels does not override that limit. A red cost below 40 can instead mean that you do not currently have enough levels. A missing output can be an incompatible book or an operation with no applicable change.

1. Check the target item and every enchantment on the offered book. For example, Fortune and Silk Touch cannot be preserved together on the same ordinary tool.
2. Check whether either input was previously combined or repaired on an anvil. The book’s history counts too; “fresh sword” does not mean “zero total penalty”.
3. Separate renaming, material repairs and existing target enchantments from this planner’s supported task. It models unenchanted targets plus single-enchantment book rows.

When changing the order can help

Before any operation, enter the books and their actual work counts and compare complete plans. A count of 0, 1, 2, 3, 4, 5 or 6 contributes 0, 1, 3, 7, 15, 31 or 63 levels respectively. A different tree can reduce repeated penalties, but cannot erase history already attached to an input.

A target with count 5 is not automatically unusable: a fresh Mending I book adds 2 to its 31-level penalty, making that step 33. A count of 6 already contributes 63, so ordinary book application cannot fit under the survival cap. Renaming alone has special behavior and is outside this calculation.

Choose what you are willing to give up

• Keep the enchantments: use a feasible remaining operation if one exists, or keep the item as it is. Mending repairs durability when eligible held or equipped gear receives collected experience; it does not reset anvil history.
• Start again: a fresh item and fresh books can avoid inherited history, but replacing only the item does not remove a book’s penalty.
• Use a grindstone deliberately: ordinary enchantments are removed; curses remain. This is a destructive choice for the enchantments you wanted to preserve, not a free history reset with all upgrades intact.

Creative mode and server modifications are separate rulesets. This guide does not claim that an unofficial command or a generic “1.20 rebalance” fixes a normal survival world.
