To create a rune, you need to acquire 1,000 of its fragments first.

To create a rune, go the Fragments tab in the Rune Workshop, and then select the necessary fragments from those you have. At the top of the screen, you'll see how many runes will be obtained after hitting the "Create" button. When fragments are fused, a rune of Simple quality is always created. You can improve the rune's quality during the next rune fusing process.

With fusing, you can create one rune of a higher class from four identical runes. For example, 4 Rare class Iron Will runes = 1 Epic class Iron Will rune. Runes of all classes except for Legendary can be fused.

To increase the rune class, go to the Fusing tab in the Rune Workshop, select the rune you need, and hit the "Fuse" button. The number of runes for fusing can be altered by the slider.

If you want to create several runes of a higher class, then use the multifusing function — it fuses eight or more identical runes.

Runes are fused for Silver and time, or instantly for Gold. The fusing cost depends on the class and number of runes, as well as on the level of the Rune Workshop. The higher the resulting class of the rune, the more expensive the upgrade process.

Fusing speed depends on the level of the Rune Workshop, and the maximum class of a rune depends on Knowledge learned in the Oracle. You can reduce the fusing time by using boosts.

If there is less than five minutes left until the fusing ends, the "Boost" button is replaced by the purple "Free" button, which you can hit to finish the process. The time for free autocomplete can increase if you have activated VIP status or certain bonuses. Please note: some VIP status bonuses allow you to fuse runes instantly.

If you have fewer than four identical runes, then the empty slots are outlined with red. This means that fusing is currently unavailable.
