Common questions
Enchantment Cost Calculator FAQ
What causes the prior-work penalty?
Using an anvil on an item records prior work, and repeated operations make later combinations progressively more expensive.
When does an anvil say Too Expensive?
For ordinary survival operations covered here, a total cost of 40 levels or more is flagged as Too Expensive.
