The Catalyst is a console located in Dornogal that lets you convert eligible seasonal non-set gear in The War Within expansion into class set pieces and older gear for transmog. It makes completing set bonuses on multiple characters much easier.

The following seasonal non-set items can be converted with the Catalyst:

• PvP Gear (Honor / Conquest / War Mode);
• All PvE Gear of Veteran Rank or higher.

Keep in mind you can only transform Head, Shoulder, Chest, Hand, and Legs armor.

The Catalyst is available from the beginning of The War Within Season 1, starting on September 10, 2024.

The Catalyst uses charges to convert non-set items into class set pieces. In The War Within expansion, the charges are called Harmonized Silk.

To convert non-set items into class set pieces, you must spend charges. The charges will accrue automatically. You will receive your first charge when a new season begins and an additional charge every two weeks.

You will receive your first charge when a new season begins and additional charges every two weeks.

Sadly, there is no catch-up system in place for Catalyst charges. When you log in to the game after a while, you will receive only 1 charge.

You can have a maximum of 8 charges on 1 character.

The Catalyst in the War Within can be found in Dornogal at 50, 54.

Interact with the Catalyst by clicking on it until you see the Catalyst window open.

Click the big "+" sign to select an eligible item from the dropdown.

Now, you will see your non-set item on the left and the resulting converted set item on the right. When you are happy with the result, hit the Transform button, and you are done.

Older gear can be converted for transmog using the Catalyst for free.

The item level of the non-set item you use in the Catalyst will affect the appearance of the class set item you will receive (Raid Finder, Normal, Heroic, Mythic).

• Raid Finder Appearance: Item Level 584-593;
• Normal Appearance: Item Level 597-606;
• Heroic Appearance: Item Level 610-619;
• Mythic Appearance: Item Level 623-632.

Other slots will be converted to non-set items with different secondary stats. You can use the conversion process on them if you are unsatisfied with the secondary stats on your non-set items.

The resulting item level will be the same as the item you put into the Catalyst. It also keeps Mythic/PvP upgrade paths, tertiary stats, and sockets.

Are Tier Set Items Created by the Catalyst Upgradeable or Do You Need to Remake the Tier with a Higher Item Level Base Piece?

You will want to remake it with a higher item level base piece unless the initial version had an upgrade path from PvP or Mythic+, and you earned currency to allow it to be upgraded that way.

The tier pieces all have specific secondary stats regardless of what item is put into the system.

Only RANDOM tertiary stats will carry over to the Tier item upon conversion. Guaranteed tertiary stats will NOT carry over.

If you deleted, destroyed, or disenchanted an eligible item that you want to use for the system, you should visit the World of Warcraft Item Restoration page for further assistance.
