Result prior uses

Prior work penalty doubles each anvil use: 0, 1, 3, 7, 15, 31 levels. Combine cheap-to-expensive to keep costs under 39.

How to use

  1. Enter prior anvil uses for both items (F3+H tooltips show them).
  2. Add the enchantment level cost of the combination.
  3. Read the total and the survival feasibility.

Examples

Item used twice + fresh book, cost 4
Output: 3 + 0 + 4 = 7 levels; result counts as 3 prior uses.

Frequently asked questions

Why does cost double each use?

Prior work penalty is 2^uses - 1 levels per item: 0, 1, 3, 7, 15, 31. It is why enchantment order matters.

What is the survival cap?

Anything over 39 levels shows "Too Expensive" in survival, no matter how many levels you have.
