Here’s a little guide to Griffin School Witcher Gear. Where to get it, what you need to make it, and what the Grandmaster set does.
Of course there are spoilers ahead.
Buy the first and second maps from the armourer in Midcopse. Read them to start the quests “Scavenger Hunt: Griffin School Gear” parts one and two. Do the quests.
Dragonslayer’s Grotto for the armour, boots, trousers, and gauntlets. Silver sword diagram is in Lornruk. Steel sword diagram is in Hindhold.
Then – around level 10 – you should prepare to craft your first set of Griffin School Gear.
You only need a Journeyman armourer to craft the first set of Witcher armour for you, and there are plenty around Velen, Novigrad and Oxenfurt. You’ll also need a Journeyman blacksmith to make the swords. Make sure you have all the crafting materials you need first (craft them yourself rather than buy them from vendors), and also have the money to pay for the crafting itself.
The first set of Griffin armour, boots, gauntlets and trousers only have one slot for Glyphs, so fill that with something of your choosing. The initial Griffin School swords both have one slot each, so put a Runestone in each of those.
Next you need to work your way through the various Scavenger Hunt quests for the upgrade diagrams – Enhanced, Superior, then Mastercrafted.
It’s worth remembering that in The Witcher 3 you’ll always need the previous set to make the next set of armour/weapons. With a couple of exceptions.
Get the Master Armourer’s Tools from Skellige for Yoana at Crow’s Perch, and help Hattori resolve his problems in Novigrad. Helping Yoana and Hattori will unlock master armourers and blacksmiths, which you need to continue upgrading your Witcher armour and weapons.
Once you have Mastercrafted armour and weapons you’re good to take on The Wild Hunt at the end of the base game. You don’t need Grandmaster sets to fight The Wild Hunt. In fact: Grandmaster sets are a DLC thing – they’re part of Blood and Wine.
To get the Grandmaster Griffin School Gear:
Firstly, you need to initiate the quest “Master Master Master Master!” with Lazare Lafargue in Toussaint. Once you’ve done that you can then set out to look for the Grandmaster crafting diagrams.
The Grandmaster Griffin School diagrams can be found at Fort Ussar Ruins and Mont Crane Castle in Toussaint and the associated Scavenger Hunt quest is recommended for level 40 players.
Once you have the diagrams, turn them in to Lazare Lafargue and he’ll then be able to craft Grandmaster items for you. He crafts both weapons and armour. You need lots of Enriched Dimeritium Ingots, Plate, and Ore, which are expensive, so get grinding for money.
If you’re going to make multiple sets of Grandmaster Witcher Gear you should start grinding for all that Enriched Dimeritium that you’re going to have to make. Start collecting Orichalcum, Acid Extract, and Dimeritium Ore.
Each Grandmaster set requires approximately five (5) Infused Slyzard Hides, five (5) Enriched Dimeritium Ingots, and five (5) Enriched Dimeritium Plate. Which are expensive to make and can only be made by Lazare Lafargue. It’s cheaper to craft your own, though, than buy ready made from Lazare.
These are required levels for crafting Griffin School Witcher items:
Basic Griffin gear – level 11
Enhanced Griffin gear – level 18
Superior Griffin gear – level 26
Mastercrafted Griffin gear – level 34
Grandmaster Griffin gear – level 40
Grandmaster Griffin School Gear gives these bonuses:
3 pieces: After using Stamina to cast a Sign in its standard mode, the next Sign cast within 3 seconds will be cast in standard mode without using Stamina.
6 pieces: The size of Yrden traps is increased by 40%. While you are within an Yrden trap, Stamina regeneration is increased by 5/s and Sign Intensity by 100%, and damage is reduced by 20%.
This is a beauty of sticking with Griffin School Gear – the Grandmaster Gear bonuses. Quick-fire Sign use for wearing three pieces, and extended Yrden for wearing six pieces. The extended Yrden trap is worth it too; not just for the combat bonuses, but also for the cool purple light show. See the video below for an example of that.
