The Cat school light armor set is ideal for an agile, fast attack playstyle. Its grandmaster set bonuses are:
- Strong attacks increase Fast attack damage by 10% for each piece of the set for 5 seconds
- Rear attacks deal 50% more damage and stun at the cost of 1 adrenaline point
To upgrade the set to Grandmaster in Blood & Wine, travel to Beauclair and speak with the Grandmaster Smith to start the Scavenger Hunt: Grandmaster Feline gear quest.
The highlighted quest location will take you to an estate. To get inside, walk around the wall until you find the scaffolding and use it to climb over.
After defeating some bandits and talking to an NPC, head into the red house; inside, you will find a painting that contains the Feline armor diagram. Read the note that came with it for the next diagram location.
The next highlighted map location is a bandit camp – you’ll have to fight though a horde of bandits and then walk into the central tower and go right. You’ll find a chest with the Feline trousers and boots here, and a note for the next location.
At the final location you’ll find a cave. After killing the archespores, loot the bag at the end of the cave to get the last three diagrams: steel sword, silver, and gauntlets.
You can now travel back to the grandmaster smith to craft the Feline set. Make sure that you have all the mastercrafted Feline pieces – you’ll need them to craft the Grandmaster gear.
