As an MMO, Lost Ark has many ways for players to earn rewards between sailing, high-level gear, or collectibles in the game. Collectibles are one of the longest grinds of all game features, and Mokoko Seeds are the main item in this category.
There are thousands of Mokoko Seeds to collect all over Arkesia. You may encounter them in various content in the game, for example: dungeons, questing, or islands.
Blackrose Chapel is a map from East Luterra and you'll need to spend some time collecting all the seeds there as there are 13 in total. But there are not many seeded maps in the game.
Some of these Mokoko seeds will hide behind secret passages. You'll find two of these Buy Lost Ark Gold seeds in the house below the Church Graveyard. Even though it doesn't seem to allow it to be opened by design, you can enter directly through the door.
In the west of the map, there is a seed hidden behind a secret passage, which you can easily spot when looking for it. Reach where the red line is and you'll find a burnt house. When you enter, you will automatically enter the secret passage. There you'll find three Mokoko seeds, but it's important to note that they're so far away from each other that you'll need to do some exploration to find them.
Seeds in the north of the map will also take you to Vista, so you need to be very careful when collecting them.
Players will encounter various unexpected events when collecting seeds, and sometimes encounter powerful enemies. If you do not have enough strength, it is best not to explore those areas easily. If you want to improve your own strength faster, the best way is to spend Lost Ark Gold to buy excellent items, which are very helpful for improving your character's attributes. When your Lost Ark Gold is insufficient, you can also seek help from MMOWTS, they will always provide you with sufficient Lost Ark Gold.
