Fire Monksβ Prayerbook is an Elden Ring key item found in Liurnia of the Lakes region and serves the same purpose as the Assassinβs Prayerbook. This means that by finding the Elden Ring Fire Monksβ Prayerbook, youβll be able to unlock new Incantations for your Tarnished.
To do this, however, you must first find the Fire Monksβ Prayerbook in Elden Ring; then, you need to locate the NPC interested in this item. Here is everything you need to know about this book.
Where To Find the Elden Ring Fire Monksβ Prayerbook
The Elden Ring Monksβ Prayerbook is in an enemy camp found along the southern road in Liurnia at the location marked on the following map.

This camp can be reached by following the path south of the Lake-Facing Cliffs Site of Grace. Although small, the camp is quite rich in loot. After you clear the enemies, make sure you retrieve the Fire Spur Me Gesture near the large fire in the camp.
There are also some Smoldering Butterflies here, and obviously, the Fire Monksβ Prayerbook found on a corpse near one of the tents (pictured below).

Great, so now that you know where to find the Elden Ring Fire Monksβ Prayerbook, letβs see what to do with it.
How To Use the Fire Monksβ Prayerbook
Once you get the prayerbook, check your inventory to spot the following description: βPrayerbook of the Fire Monks, who came from the Mountaintops of the Giants far to the north. Can be given to a learned cleric to gain access to the following incantations: O, Flame!, Surge, O Flame!β
If you wonder who is the learned cleric interested in this book, the answer is Brother Corhyn in Roundtable Hold. So, fast travel to the hold, look for him and then choose to give a prayerbook when talking to him.

By giving the Fire Monksβ Prayerbook to Brother Corhyn, youβll unlock the O, Flame! and Surge, O Flame! Incantations, and heβll be willing to help you study them for a total of 11.500 Rune. Last but not least, keep in mind that Brother Corhyn will eventually relocate to Altus Plateau, just north of the Altus Highway Junction Site of Grace, once you progress through the game.
