The Book of Sin is a Quest item inLords of the Fallen. Players can obtain this item once they explore Pilgrim’s Perch in the Umbral Realm. Exploring the area in Axiom is not wrong by any means, but certain platforms and slopes won’t appear inLords of the Fallen.
The Quest actually belongs toExacter Dunmirewho is the NPC players’ first encounter in Skyrest Bridge. The Exacter will ask for more items in the future and lampbearers decide if they wish to give him the items or not. Here’s how people canget the Book of Sin inLords of the Fallenand how to use it.

How To Get Book Of Sin Location In Lords Of The Fallen
The Book of Sin inLords of the Fallenis located inside the Umbral Realm, hidden in an Umbral Belly. Players must first travel to the location since it’s a bit tricky to reach.
First, fast-travel to thePilgrim’s Perch Bellroom Vestige inLords of the Fallenand turn right through the only path. At the end of the path, there are a couple of enemies including pilgrims who attack with Spells and worshipers who cower in fear. If desired, ignore them and go left through the narrow wooden passage.

Once lampbearers emerge from the shack, use the spinning wooden platform to jump to the other side. Again, ignorethe large enemy inLords of the Fallenat the end of the long platform but be careful as it can perform a quick head smash that causes decent damage.
Go down the ladder at the end of the platform to find another one nearby to the right. This one, however, is surrounded by moths, which means that it should be used in the Umbral Realm. Go to the world of the dead and descend the stairs to find several skeletons and a large moth enemy. Run past them and climb the ladder.

Be careful as a nearby enemy will try tohit players with ranged Spells. Take cover and climb the second ladder to reach a narrow white bridge. Don’t use the Emergence Effigies at the end as lampbearers need to stay in Umbral.
Hop down to the right and descend the long ladder ahead. Use the bone slope to go down to find several skeleton eggs. Head down one more slope where there are even more skeleton eggs.

Ignore them if desired and focus on Soulflaying the Umbral Belly in the middle to obtain the Book of Sin inLords of the Fallen.
How To Use The Book Of Sin In Lords Of The Fallen
The Book of Sin can be given to Exacter Dunmire at Skyrest Bridge to proceed with his Questline. The Exacter doesn’t necessarily say to bring him the Book of Sin. Instead,he asks players to retrieve any itemsthat can be considered proof of the Hallowed Sentinels' heretical deviations and practices. That’s because he wishes to return them to the true light of Orius.
Upon reading the Book of Sin description, players will find out that the book actually contains the sins of former pilgrims who got accepted into the Hallowed Sentinels.

Lords of the Fallenis out on PC, PS5, and Xbox Series X/S.
