Latest changes
Update for kalandra league
Data has been updated for 3.19.- New bases have been added : Bone Ring, Bone Spirit Shield
- New items have been added : Calling Wand, Convening Wand as well as Lake rings.
- Harvest was nerfed again but you can still access the old version with the toggle on the top left of the emulator
- The data structure and logic was changed to accommodate for multiple modgroups per affix to be inline with the game change (this might result in some bugs here and there so don't hesitate to let me know.)
Simulator overhaul
You can now simulate multiple step crafting strategies on craft of exile using the new simulator.Ex : Roll for +1 spells, imprint, reforge phys, return to imprint and let the tool repeat your steps thousands of times to see how effective your crafting strategy is.
Almost everything that is lacking from the calculator is now available in the simulator including : Open prefix/suffix, Number of prefix/suffix, Eldritch crafting, Harvest crafting, Pseudo conditions and more!

What's Craft of Exile?
Craft of Exile is an online tool with the goal of making it easier for players to find out the best and most cost effective ways to achieve their crafting goals in Path of Exile. There is no need for any installaton or downloads, everything is right here on the browser.
The key features :
New features are added regularly, please check out the Changelog page to see what is new and what is in the works at the bottom of the page.
The key features :
- Compute an estimate of the odds to hit a certain mod combination on an item given a crafting method (Fossil and essence crafting included).
- Find out the outcome of a slam (exalt, conqueror orb, regal) by building your item and blocking mods.
- Simulate crafting results with the mass simulation function and see statistical distribution of mods as well as an item showcase of the most likely results.
- See the total converted costs in chaos of your crafting setup in relation to your league (You can set your own custom prices if need be).
- Search the whole modpool to find desired mods.
- Set the iLVL of your item to optimize your results by blocking certain mods.
- And many more...

Disclaimer
This tool is a work in progress and as such do not take every result you see as a fullproof pin-point accurate number. Many features are still in an experimental stage and might require fine-tuning. I made this tool to be able to find more efficient and cheap ways of crafting while getting a better understanding of the whole system. I make it available to the community so everyone can enjoy the same advantages.
When working with high-probability calculations (<= 1/100) it is advised to double check the result via the mass simulation function with a sufficiently high count (>= 1 000 000) at the bottom before spending in-game currency. From experience, most of the calculation errors I've encountered (and since fixed) come from setups that leave the affix pool disproportionately skewed towards one mod in particular. If your setup results in this I highly recommend using simulation as an extra validation. If you do see a notable discrepancy between the calculation and simulation please let me know by going to the About page and sending me a detailed message.
