During Rogier’s quest first, you will have to fight Godrick the Grafted in Stormveil castle and look for Rogier who will then grant you his Rapier and the Glintblade Phalanx Ash of War.

Then you will have to move to the depths of Stormveil Castle where you will awaken the Ulcerated Tree Spirit and find a Stonesword Key. You will also come across an item called the Prince of Death’s Pustule.

Now you need to converse with Rogier who will tell you about the Night of the Black Knives whose mark is the Black Knifeprint. After talking to Rogier, make your way to Fia who will give you intel on the Black Knifeprint through a clue map.

After you have received the map from the Fia, go to the Site of Grace known as the Black Knife Catacombs. Beware of the undead skeletons who will attack you and the guillotine blades that will fall on you. You will also come across a necromancer enemy waiting for you on the ledge.
