Minecraft Enchantment Order Optimiser
You've got a stack of enchanted books and you want them all on one sword — this tool tells you the RIGHT order to combine them so you don't get hit with "Too Expensive". The trick is a balanced tournament-bracket combine, not a straight line. The diagram below shows you exactly.
Plan your combines
Only enchantments that can go on your item are listed. Set the level for each one — the tool uses this to work out the cheapest combine order.
Cost tip: it's much easier to earn XP in stages than to save up 30-40 levels in one go. Do each combine as soon as you have enough XP for that step, drink or trade off any surplus, then keep going. Anvils don't care how long you take.
Why the anvil order matters so much
Behind the scenes, Minecraft tracks a "prior work penalty" on every item. Every time an item goes through the anvil, that penalty doubles: 1, 2, 4, 8, 16, 32. When you combine two things, the anvil charges you a chunk of XP based on whichever input has the higher penalty — so after 5 or 6 combines on the same item, the anvil throws up "Too Expensive" and won't let you continue.
The way to beat this is to keep every item's penalty low for as long as possible. That means combining pairs of BOOKS first (which start at penalty 0), pairing those combined books together, and only touching the tool once — at the very end, when everything else is merged into one final super-book.
Three rules to remember:
- Books first. Every combine on a book is cheap. Every combine on a tool that already has enchants is expensive.
- Pair things of equal "history". Two brand-new books cost 1 XP to combine. A brand-new book plus a super-book that's been through 3 combines costs 8 XP for the penalty alone.
- Save the tool for last. The tool goes through the anvil exactly once — the day you slap the finished super-book onto it.

Enchantment combining FAQ
The anvil caps combining at 39 XP levels (40 in creative). Every time an item goes through the anvil, its "prior work penalty" doubles — 1, 2, 4, 8, 16, 32… so after just a few combines, the next one costs more than 39 levels and the anvil refuses. The trick is to combine your books in the right ORDER: pair them up like a tournament bracket instead of tacking each one onto the same item one at a time.
A hidden count Minecraft keeps on every item, starting at 0 and going up by 1 (well, doubling from 1) every time you use an anvil on it. When you combine two items, the anvil looks at whichever input has the HIGHER penalty and charges you 2 to the power of that penalty in extra XP. That's why the same combine can cost 5 levels the first time and 33 levels the fifth.
Combine books together first. Every combine on a plain book is cheap because books start with a low penalty and stay easy to work with. Once you've merged all your enchantments onto a single "super book", the last step (super book + tool) is the only combine where you actually pay for the tool's enchanting cost. This is by far the cheapest total XP.
Yes — combining two Sharpness III books gives Sharpness IV, and IV + IV gives V. It's often the only way to get max-level enchants outside of very lucky enchanting-table rolls. The optimiser above assumes you've already stacked your books to whatever levels you want and are now looking at the order to merge them.
The prior-work-penalty rule is the same on both editions. The "Too Expensive" cap in survival is 39 levels on both. There are tiny UI differences on Bedrock (the anvil sometimes shows costs slightly differently), but the underlying maths — and therefore the optimal combine order — are identical.
