While you’re at Kaer Morhen, there is a quest you can get that grants access to the legendary Witcher forge within the castle. The result of it is that you can get yourself a mastercrafted version of the Wolf school gear, which saves you needing to run around getting diagrams, at the cost of one elementa’s life anyway. Here is a walkthrough of the Witcher’s Forge questline in the Witcher 3.

The Witchers Forge (Level 30)¶

Now, if you read “Monstrum, Or a Portrayal of Witcher: Volume 2” which you could have found back in Kaer Morhen you may remember it mentioned “the mines near Kaer Morhen”. Since you’re already here and all, you might as well finish up this quest, too. In the chamber where you fought the golem - along the northern wall of said chamber - you’ll find a shrine. Yes, the same shrine where you nabbed the “Diagram: Superior Wolven Gauntlets”. Examine it and some candles will light up, and a passageway to the west will open up. Score.

Head west down the passage that opened up, then turn south to reach a chamber, where Geralt will comment on some magic nearby. Loot the room, then head up some stairs to find a hearth, which is somehow still burning, although the bellows nearby suggest the blaze isn’t quite as potent as it could be. Investigate one of the bellows and the fire itself will talk to you, claiming the forge belongs to one Radmir of Tor Carnedd. Say what you will and the voice will grow… agitated when Geralt voices his desire to poke about, ultimately manifesting as an Ifrit (level thirty). Apply some more Elementa Oil, if necessary, and don’t forget that Aard can snuff the elemental’s flames for a time.

Once the Ifrit is slain, return to the hearth - now mere embers, but still hot enough to burn you if you step on the coals - and use The Eye of Nehaleni on the wall at the back of the hearth to dispel it. Behind this wall you’ll find three chests containing various armor, most notably a suit of Mastercrafted Wolven Armor . Considering the Crowns and components you’ll save by not having to craft this yourself, it’s a worthy reward, indeed.
