Found in the Painted World of Ariandel. In the Corvian Settlement, navigate to the rooftops and into the tower with the ladder that leads to the bridge to the cliffside. Inside the tower is a drop-down which leads to a locked room with three Forlorn Corvian Settlers within. The set will be on a corpse inside.
The Slave Knight Set is renowned for possessing the best physical protection to weight ratio among all armor sets in the game, providing strong defenses against physical damage for a very light weight. It possesses equal amounts of resistance to Regular and Slash damage, and its weakest elemental defenses, against Magic and Lightning, are also equivalent.
Given its weight, it provides respectable Poise, albeit not a significant amount.
