In Lost Ark, Mokoko Seeds are one of the most abundant collectibles you can find. They can be found in just about every area of the game. When they’re found, they are a dark green but glow an even brighter green once you’ve interacted with them. Some are really easy to find, while others are a little trickier and require different prerequisites to be completed beforehand. There are eight Mokoko Seeds to seek out and collect in Great Castle within Yorn.
In order to gain access to the continent of Yorn, you need to have reached Tier 2 and have an Item Level of at least 600. All of the Mokoko Seed locations are shown below and are circled in red.

It’s important to note that some of the seeds that you can find are inside buildings. It’s also important to note that you will need a Friendliness level of at least 300 for one of the seeds in the far south. Lastly, you will need to have the song Romantic Weapon as well for one of the seeds in the southwest.
Once you’ve collected all of the Mokoko seeds in Great Castle, you will be that much closer to obtaining all 1,200 seeds. Remember, you can earn rewards for collecting Mokoko seeds by exchanging them on Mokoko Village in the continent of Tortoyk.
