What it does: Find the exact anvil combine order that minimizes XP cost and avoids 'Too Expensive!' for any Minecraft item and enchantment set. Free, instant, conflict-aware. Everything below this notice that explains the method is still readable.

? How this is calculated

Every anvil pass adds a prior-work penalty of 2^n − 1 levels (n = times that item has been on an anvil before), charged on both sides of every combine. Moving an enchantment costs its level × a rarity multiplier (1 for common/uncommon, 2 for rare, 4 for very rare, from a book). The optimizer searches every legal way to group and order your books — including partial deliveries onto the tool along the way, not just one final merge — and returns the sequence with the lowest total cost where no single step reaches 40 levels. It assumes one freshly made book per enchantment; already-used books or items carry their own prior work and will cost more than shown here.
