How to Masterwork Your Gear in Diablo IV

Open Masterworking at the Blacksmith and select an eligible item. Spend the displayed materials to raise its Quality. At Quality 25, you can apply the Capstone Bonus, which improves one randomly selected affix by 50%. If the bonus lands on an affix you do not want, the reroll option can change that affix without resetting the item's Quality.

1. Choose the piece you expect to keep

Inspect the item's normal affixes, its Legendary power or other special properties, and how it fits the build you play. Quality upgrades cost resources, so prioritize gear you will use for a while. An item with stats your build actually needs is usually a better first target than one with a higher-looking number on a stat you rarely use.

If you are choosing between two pieces, equip each one and check what changes. One may let you reach a stat goal elsewhere in your build, freeing another slot for damage or survival. Check whether you want to make other crafting changes before investing in Quality. Having the item close to its intended setup makes the Capstone outcome easier to evaluate.

2. Raise Quality at the Blacksmith

1. Visit a Blacksmith and open Masterworking.
2. Select the eligible item you want to improve.
3. Check the item's current Quality and the material cost shown in the preview.
4. Apply the upgrade and inspect the new Quality.
5. Continue toward Quality 25 if you want the Capstone Bonus and have enough resources.

The cost shown in the menu is the one to use for budgeting. You can raise Quality in several sessions as you earn more materials. If you are working on more than one piece, decide whether you want a quick improvement across several slots or a Capstone on the most important piece first. Keep track of which item you selected, particularly if you have two copies of the same gear.

3. Apply and inspect the Capstone Bonus

At Quality 25, use the final Masterworking option to apply the Capstone. The game selects one affix to receive the 50% improvement. It can land on a stat you were hoping to improve or on a different eligible stat. Check which affix received it and compare the change with what your build needs.

Do not judge the outcome solely by whether it landed on the first affix you had in mind. A bonus to a defensive stat might solve a problem you were compensating for elsewhere. Test the item in the activity you are preparing for before rerolling a useful result. If it is still the wrong bonus for the build, return to the Blacksmith and check the reroll cost.

4. Reroll the Capstone without rebuilding Quality

Use the Blacksmith's option to reroll the Masterworked affix. Read the cost before confirming, particularly if you need those materials for other slots. Your Quality stays in place, so you do not need to pay for the entire climb to 25 again. The next affix is still a roll. The service does not let you directly choose the result.

Set a budget before making repeated attempts. If you have several items that need basic upgrades, keep enough material to improve them as well. A Capstone on the ideal stat can be helpful, but spending everything to chase it can leave the rest of the build behind. Keep a usable bonus if it is already supporting the activity you want to clear.

5. Fix a missing upgrade or reroll option

Check that you are in the Masterworking tab with the intended item selected. If the final upgrade is unavailable, inspect its current Quality. If Quality is already 25, check whether you have applied the Capstone and whether you have the required materials for the next action. The preview and tooltip are more reliable than comparing the screen to an older video.

Keep Masterworking separate from Tempering when reading the menus. Tempering applies an extra affix from a recipe, while Masterworking raises Quality and eventually grants the Capstone. If you are looking for a particular Temper recipe, return to the Tempering tab. If your goal is to change the affix boosted by the Capstone, stay with the Masterworking controls.
