On this page, you can find detailed walkthroughs for obtaining every diagram for every upgrade level (basic, enhanced, superior, and mastercrafted) of the Bear (Ursine) Witcher set, one of the best armor sets in the game. Keep in mind that you need to craft every level of the set in order to upgrade it to mastercrafted.
The Ursine set is ideal for a tanky build that focuses on strong attacks, providing you with lots of armor.
Note: if you’re having trouble finding the chests with the diagrams, look for a Wolf Head symbol; examining it will give you a general area to search.
Buy the map from the armorer in Oxenfurt and use it. Head over to the northernmost island (An Skellig) in the Skellige Isles -- you will have a quest marker there, inside a ruined castle.
Ursine Chest, Boots, Trousers, Gauntlets
Once you get inside the hall with the 4 locked doors, push a lever at the end of the hall to open them. One of the rooms will have an entrance to cave -- go inside and follow the way to the main castle hall, where you will find the armor diagrams, and read the chronicler’s notes in your inventory to get the locations for the other Ursine diagrams.
The Silver sword will be found on a skeleton on Ard Skellig to the east of Kaer Trolde, the crossbow inside a large cave on Spikeroog island (northwest on Skellige map), and the steel sword from the basement of a ruined house in south-eastern Ard Skellig.
Enhanced Ursine Chest Armor is found in a cave called “Grotto” off the south-eastern end of Ard Skellig. Be wary of the 3 bandits guarding the chest -- they were level 26, at least for me.
Also, make sure to loot everything in that area, as there are some nice diagrams and potion recipes in there as well.
Enhanced Ursine boots can be found in a troll cave in southern Ard Skellig, just under one of the places of Power. You have to kill 3 level 16 trolls to loot the chest.
Enhanced Ursine trousers are found on a small island off the west coast of Ard Skellig. You will find a partially-submerged cave that will have a chest with the diagram. You can ignore the high level drowners here.
The Enhanced Ursine gloves can be found on top of a ruined wall northeast of the village of Rogne on Ard Skellig.
Enhanced Ursine Steel Sword -- On a small island to the west of Ard Skellige, inside the fortress of Kaer Almhult, directly north of where you find the enhanced ursine trousers. The exact location is up some stairs, on the right side of the main courtyard of the fortress keep. This area is a pirate base so be prepared to fight lots of level 12-14 pirates.
Enhanced Ursine Silver Sword -- inside a ruined fortress north of the druid tree at Gedyneith in northeast Ard Skellig. You have to go all the way down into the cave. This area has lots of alghouls, which makes it one of the most difficult diagrams to obtain. The Alghouls are level 21 (to help kill them, use Axii when they turn red and grow spikes).
Superior Ursine Chest, Boots, Trousers, Gauntlets -- All the superior armor pieces can be found in central Velen, north of Hanged Man’s Tree. The chest is located inside a cave, and will be protected by a group of level 6+ Nekkers and Nekker Warriors.
Superior Ursine Steel Sword -- found directly at the Ruined Tower travel post. It is guarded by a level 25 Earth Elemental, but you don’t have to fight it if you’re careful. The diagram box is in one of the corners of the ruined tower structure.
Superior Ursine Silver Sword -- in a cave in southern Velen, to the west of the Croockback Bog. Look for the box with a dead body leaning against it. This is the same cave where you do the “Swamp Thing” Contract. The cave has two entrances -- one hidden by an illusion -- the other one open.
Mastercrafted Ursine Chest, Boots, Gauntlets, Trousers -- Destroyed Bastion, in the far south of Velen, to the east of Bald Mountain. The chest is found directly on top of the whetstone icon on the map. You don’t have to fight anything, although the area is guarded by a lvl 19 cyclops, and also has a level 32~ Basilisk nearby.
Mastercrafted Ursine Silver Sword -- far south Velen, You will see a small island with a drowner nest on it, that’s where the chest is buried. Also, don’t forget to loot the extra underwater loot chest just to the right of the island.
