Catalysts are currency that improve crafting on jewellery. They add quality to the crafting mods on rings, amulets and belts.

Why this matters

Catalysts make jewellery crafting stronger, letting you roll better mods.

Step-by-step

  1. Use catalysts on rings, amulets or belts.
  2. Apply them while crafting to add quality.
  3. Higher-quality crafting gives better mod values.
  4. Match the catalyst to the mod you want to improve.
  5. Use them on jewellery worth crafting.
  6. Combine with other currency for the final roll.

Key tips

  • Use on jewellery only
  • Add quality to the craft
  • Match catalyst to the mod
  • Craft gear worth it

Common mistakes

  • Using catalysts on the wrong slots
  • Wasting them on junk bases
  • Ignoring mod quality

Practical notes

Catalysts add quality to rings and amulets that boosts a specific modifier, so apply the catalyst that matches your item’s best affix. Stack the same catalyst to raise that modifier further, but stop when the affix is capped.

Use them on gear you will keep, because the quality is permanent. Pair the right catalyst with the right base to squeeze real value. A well-catalyzed ring or amulet can rival a rare upgrade.

Stack the same catalyst to raise the chosen modifier, and stop when that affix is capped so you do not waste catalysts on a finished item.

Stack the same catalyst to raise the chosen modifier and stop when that affix is capped, so you never waste catalysts on an already finished item.

The crafting guide and currency guide show which catalyst pairs with which modifier.
