The Cashew Fruit is an entry in your Adventurer's Tome in Lost Ark. In most cases, you can only find it on the Tortoyk Continent, where it sometimes appears randomly.
Where is the Cashew Fruit in Lost Ark?
We have found that Cashew Fruits are more likely to drop from larger monsters. You can increase your chances of finding the Cashew Fruit by going straight for the special monsters.
You cannot earn collection items in a set way; monsters will randomly drop them, so you basically have to resort to old-fashioned farming and luck. The Cashew Fruit looks like it would in real life. They are similar in shape to bell peppers, but they are only red in the game.
If you are going to place it in an Adventurer's Tome, take it to a secluded, safe location. Mokoko Village is usually your best option.
Open your Inventory by pressing the I key and then right-click on the Cashew Fruit. You will receive a notification that the Cashew Fruit Collection has been added to the Adventurer's Tome.
