COST LOGIC

Why Enchantment Order Matters

Every anvil use adds a prior-work penalty. Combining the same books in a different tree can change both the total levels you spend and the cost of the final step. A step costing 40 levels or more cannot be completed in Survival, even when the enchantments themselves are valid.

RESULT QUALITY

Exact Optimal vs Best Found

Exact Optimal

With up to eight sacrifices, AnvilPilot completes the full search and proves that no plan ranks better under the selected objective and tie-breakers.

Best Found

With nine to 32 sacrifices, a deterministic bounded search returns its best result without claiming mathematical optimality.

SUPPORTED RULESET

COMMON QUESTIONS

FAQ

What does prior work mean?

Prior work is the number of earlier anvil operations in an item's history. The penalty follows 2ⁿ − 1, so it grows quickly.

Why can a valid enchantment plan still be Too Expensive?

Survival blocks any single anvil step at 40 levels or more. Earlier combinations can raise the final item's prior-work penalty past that limit.

Can I share a calculation?

Yes. Copy Share Link stores the validated input in the URL hash. It does not create a server record and the hash is not part of the canonical URL.

Does a mixed book keep every enchantment?

No. When a book is applied to an item, enchantments that do not apply to that item are discarded and shown as a warning.
