The original Wolf School treasure hunt begins in Kaer Morhen, at a ruined signal tower with a magical portal. The area has a long history of troublesome loot and interaction states on some platforms.

● Quick Answer

At the ruined signal tower near Kaer Morhen, read Hieronymus’s notes, investigate the portal mechanism, find the missing crystal, activate both crystals with Aard and enter the portal to retrieve the diagrams. The Grandmaster Wolven set in Toussaint is a special case: it can be crafted without first providing Mastercrafted Wolven pieces.

Read the corresponding treasure map or quest note to add markers. Some diagrams can be picked up without the map, but finding every piece is easier with the quest active.

Before leaving a one-time quest area, inspect the relevant chest and document.

Clear walkthrough

Do it in this order

01

Reach the tower during the Kaer Morhen chapter

Approach the ruined signal tower near the fortress and read the notebook to begin the primary Wolf School treasure hunt.

02

Repair the portal first

Investigate the mechanism with Witcher Senses, locate the missing crystal nearby, and set it into its holder.

03

Charge it with Aard

Apply the Sign to the appropriate crystals to open the portal. Check the quest objective if you are unsure which mechanism remains inactive.

04

Find the base diagrams

Enter the portal and collect the diagrams. If the chest seems inaccessible, verify that the quest and portal stages are complete, save separately and reload.

05

Craft Grandmaster directly if desired

For the Grandmaster Wolven plans in Blood and Wine, the usual Mastercrafted-item prerequisite is waived. Visit Lafargue with the diagrams and ingredients to check the recipe.

The old “cannot loot chest” bug is not proof that every current update still has the bug. If the chest fails, make a fresh save, reload and verify quest state before trying a different build. Do not delete saves.
