Overview
Scavenger Hunt: Grandmaster Ursine Gear is a Blood and Wine treasure hunt in Sansretour Marsh, unlocked in Master Master Master Master!. It follows Junod of Belhaven, a witcher of the Bear School who came here on a contract.
The collapsed house
Between Flovive and Tufo stands a partly collapsed house. Behind it, clear the rubble from a large hole to reach a small cavern. A chest in an alcove on the right holds three diagrams (silver sword, armor and gauntlets) and a note. Deeper in the tunnel is a separate treasure guarded by wraiths at night.
Owl Eye Grottos
The note points north to the Owl Eye Grottos. A giant centipede attacks soon after Geralt drops in. Opposite where it appeared, by the waterfall ledge, blast a rock wall with Aard to find Junod’s note asking to follow his marks. The marks lead to another river and a second centipede. In the same room, a skeleton holds the last three diagrams (trousers, steel sword and boots) and Junod’s journal.
The grottos are also the setting of Contract: The Tufo Monster, so the two quests can be done together, though the contract’s enemies are much stronger.
