The easiest way to get all the markings on the map is to buy Ibrahim Savi's first map, which will add all the areas to look for these diagrams.
All locations are on Ard Skellig this time though spaced out. The boots diagram is found in an unmarked cave southeast of Wild Shore (the same cave Farting Trolls is found in). Unfortunately these trolls aren't civil and will try to attack you so kill them off then look around the rubble where you'll find the chest with the diagram near a broken boat.
The armor diagram is found in the Grotto (the same cave that's part of The Sad Tale of the Grossbart Brothers). Make your way all the way around to the last chamber and where the three brothers are, then kill them off. The chest in question is in the southern part of the chamber, near one of the bed mats.
The silver sword diagram is found at an unmarked ruin northeast of Kaer Gelen. You'll likely be attacked by a group of harpies as you enter this fortress, so take care of them before proceeding further, as just as you head into the interior, alghouls appear. Make your way through the ruins and the tunnel before you find the last room with yet more alghouls. After they're defeated, you can find the chest opposite of where you entered.
- During one of his numerous adventures, Geralt got his hands on a map covered with strange markings. He quickly deduced that they indicated the locations of hidden witcher caches and, intrigued by the chance of discovering long-lost crafting schematics, he set out to find them.
Geralt found all the caches marked on the map and recovered the crafting schematics contained therein. With these in hand, he could add life-saving improvements to his combat gear. He did not know how many more such caches remained undiscovered in the world - but hoped one day he would have the chance to find more.
