About

AusCraft is a Diablo IV fan site: three sites sharing one account and one set of game data.

The three sites

• d4.auscraft.games holds the guides and the season pages. The Season 15 writing covers the secrets read out of the game files, the Echo of Tristram route and Deckard's Journal Map.
• d4comp.auscraft.games is the Gear Comparison. Give it an item and the one you are wearing and it prices the swap, damage and survivability apart, and names what it could not price rather than leaving it out.
• d4theorycraft.auscraft.games is the Character Planner: skill tree, paragon boards, mercenaries and talismans, with a damage figure built from the pieces rather than typed in.

Where the numbers come from

Almost everything on this site is read out of the game's own extracted files, from DiabloTools/d4data, which is published under the MIT licence. Skill coefficients, paragon node magnitudes, affix bands, gem and rune tables, mercenary talents and the board art all come from there, and the copy of the data is kept level with the build that is live in the game rather than a test realm.

Where a number cannot be read from the files, it is measured against a real character sheet and the measurement is recorded beside it. Where it can be neither read nor measured, the page says so instead of estimating.

Reading your own gear

You can drop a screenshot of an item, a paragon board or your character sheet onto the planner and it will read it. That reading happens in your browser: the image is not uploaded, and nothing is sent to a server unless you press Share on a result. The privacy page sets out the whole of what is kept.

Advertising

Advertising covers the hosting, and it is labelled where it appears. Gold selling, boosting and account trading are turned down at any price. Nothing on this site is for sale.

Getting in touch

If a number here disagrees with your own tooltip, send the screenshot. The contact page has the address and what to include.
