It is very similar to the Royal House Scroll we found in Limgrave, but it has a different purpose, and it is a bit harder to acquire.
Basically, the Elden Ring Assassin Prayerbook allows you to unlock new Incantations for you Tarnished, but you have to know where to find it and how to get it.
Last but not least, you also need to know where to deliver the Assassin’s Prayerbook in Elden Ring or who to give it to.
Throughout the following guide, we’ll cover all these questions.
Elden Ring Assassin’s Prayerbook Location – Where To Find
The Assassin’s Prayerbook in Elden Ring is in the Roundtable Hold’s basement, but before looking for it, you’ll need three Stonesword Keys.
These items can usually be found in dungeons, but you can also buy them.
For example, the Weeping Peninsula Isolated Merchant found west of the Limgrave Walking Mausoleum sells 3 Stonesword Keys for 2000 Runes each.
Once you have 3 Stonesword Keys, return to Roundtable Hold.
Now, from the central room, follow the southeastern corridor to find Smithing Master Hewg working on his anvil.
Next, descend the stairs nearby to get to the basement, then turn left, and around the corner, you’ll see a fog wall.
Use the first key on the Imp statue to remove the fog.
In the next room, on the left side, there is a chest containing Crepus’s Black-Key Crossbow. Make sure you get it.
Now, use two keys on the next Imp statue (also on the left side), and in the next room, you’ll find another chest near some barrels.
Loot it to get the Assassin’s Prayerbook. Now, the obvious question is what to do with it.

In return, you’ll unlock the Assassin’s Approach and Darkness Incantations from his shop.
One important aspect worth mentioning here is that Brother Corhyn will eventually leave Roundtable Hold later in the game. When this happens, you’ll find him in the Altus Plateau region, just north of the Altus Highway Junction Site of Grace.
Make sure you also bring him the Fire Monks’ Prayerbook before he leaves.
