To get collectibles such as Grangor's Tooth, you will need to farm monsters and enemies on specific continents in Lost Ark. Certain enemy types may drop certain items. Yet, it seems the drop rate for collectibles is more or less spread across all enemies on a specific continent in the game.
So, for example, if you are trying to get Rethramis collectibles for your Adventure book, you will need to farm on Rethramis and Rethramis alone.
The game will also tell you how many collectibles you need to complete that item. The collectibles to the left of the Adventurer's Tome generally have a higher drop rate than those to the right. But to counter this, you only need to find fewer items for those on the right.

Because of this, do not let any enemy survive as you progress through each continent. Kill them all and then some, as this is the only way to get the collectibles. It may take a while, but you can speed these up by playing with friends and wandering around the areas slaughtering everything with speed and finesse.
