This section covers finding the superior diagrams.
The easiest way to get all the markings on the map is to buy Ibrahim Savi's third map, which will add all the areas to look for these diagrams.
All the diagrams for this quest are located in Velen and some can be found early on enough you might have found them before getting the map.
All the armor diagrams are found in a cave northwest of the Hanged Man's Tree (the same cave you can visit during A Deadly Plot). If you don't have that quest active, you'll find several nekkers and a nekker warrior just outside the entrance. Head inside and as the path curves, you'll find a small alcove to the left, with one of the chests here containing the armor, boots, gauntlets, and trousers diagrams.
The steel sword diagram is found at the Ruined Tower, though guarded by an Earth Elemental. Once it's dead, look on one of the broken floor pieces on the eastern side to find the chest (it's half hidden behind a large tree and a nearby bush).
The silver sword diagram is found in a cave on the edges of the bog, southwest of The Orphans of Crookback Bog (the same cave during Contract: Swamp Thing). Note that there's actually 3 entrances into this cave so even if you haven't progressed far enough in the main questline to get The Eye of Nehaleni, you can still get inside. If you don't have the eye, keep heading west until you find a cave marker noting the one open entrance. If you have the eye though, simply use it on the area the quest marker indicated on the map. If you haven't already killed Ignis Fatuus and you took the one open entrance in, you'll have to fight some foglets and Ignis Fatuus himself before you can find the diagram. If you used the hidden entrance the map led you to though, head in to fight a foglet, then stick to the wall on the left to find a body with the chest behind him containing the diagram.
