Mastercraft armor is the top tier of armor in the base game of The Witcher 3: Wild Hunt, and only one person can forge it. Her name is Yoana, and she works the forge at Crow’s Perch in Velen. To open her mastercraft services, you need to finish the secondary quest Master Armorers, which has a suggested level of 24 but can be started much earlier without any risk of locking yourself out.
Quick answer: Finish the Master Armorers secondary quest to unlock Yoana at Crow’s Perch, the only crafter who makes mastercraft armor. The steps below cover the tools, the archgriffin gland, and the armor test.

What you need before starting
The quest spans two regions, so a little setup saves time. Make sure you can reach each location before committing to a full run.
- Access to Crow’s Perch in Velen, reached during the Bloody Baron main quest chain.
- Access to Skellige, specifically the island of Undvik, where the smithing tools are kept.
- A character strong enough to beat a higher-level Ice Troll and an archgriffin.
- Silver sword oils help, with Ogroid Oil for the troll and Hybrid Oil for the archgriffin.

You can also trigger the quest by asking the armorer at Hierarch Square in Novigrad or the armorer at Kaer Trolde keep in Skellige about mastercraft gear. They point you back to Fergus and grant a small extra journal entry, but the quest plays out the same way.
Get the smithing tools from Clan Tordarroch Forge
The tools sit inside the Clan Tordarroch Forge on Undvik, the southwesternmost island in the Skellige archipelago. If this is your first time in Skellige, progress the main story through Destination: Skellige, attend the wake that starts The King is Dead, Long Live the King, and finish that quest so Crach offers you The Lord of Undvik. You will usually pass through the forge area while doing The Lord of Undvik.

Test the armor to finish the quest
Once the armor is ready, Harmon insists both sets be tested by firing crossbow bolts at the wearers. Geralt wears Yoana’s armor while a villager wears the piece credited to Fergus. All you do is wait for the shot.
You must agree to the test. If you refuse, the quest fails, Yoana leaves Crow’s Perch for good, and you lose the only master armorer in the base game.
Yoana’s armor wins the test. Harmon declares the forge hers and pays her. Fergus prepares to leave, but Yoana invites him to stay on as her assistant, reversing their roles. She hands you the Diagram: Mag Deira cuirass on the spot.

Rewards and how to confirm it worked
After the test, meditate and wait one full day so Yoana can finish her gift. Return to her to collect the medium Witch Hunter’s Armor, which completes Master Armorers. Her shop now offers mastercraft armor crafting, and you can confirm this by opening her crafting menu, where the top-tier Witcher sets appear if you own their diagrams.
| Reward | Where you get it |
|---|---|
| Deithwen (silver sword) | Chest at Clan Tordarroch Forge |
| High-quality smithing tools | Chest at Clan Tordarroch Forge |
| Diagram: Mag Deira cuirass | From Yoana after the armor test |
| Witch Hunter’s Armor | From Yoana one day after the test |
| Mastercraft armor services | Yoana’s shop at Crow’s Perch |
With Yoana unlocked, the mastercraft Witcher sets become craftable once you own the right diagrams, which you find through the various Scavenger Hunt quests across Velen and Skellige. The sets themselves require level 34 to wear, and each piece needs the previous tier of that item, so keep your earlier gear. For the matching mastercraft swords, you also need Master Blacksmith Hattori in Novigrad, since Yoana only handles armor.
