To farm Book of the Priest in Lost Ark, players will need to farm-specific enemies in the Rethramis continent in Lost Ark. The drops for the books, among other collectibles, seem to be random and not specific to certain enemies in the game.
We received our Book of the Priest from Toxic Grave Robber, Poison Arrow Grave Robber, Hungry Grave Keeper Ghost, and Red Whitebeak. This means you should be able to get drops from any enemies.
How to get the Book of the Priest in Lost Ark
To get the Book of the Priest in Lost Ark, players need to simply kill various enemies in Rethrasmis. Farming specific enemies in Rethramis is pointless as any enemy could drop this. Instead, progress through the game, and you should eventually get enough of the Book of the Priest.
In time, killing enough enemies will net you the required ten Book of the Priest you need to complete it in the Adventurer's Tome. So keep killing enemies to fill the rest!
