Where to Find Sung Jin-Woo & Requirements!

To start, head over to Scorched Ruins. This is where you’ll find the NPC that allows you to unlock Sung Jin-Woo. Once you’re there, interact with the NPC to check the required materials. Unlocking Sung Jin-Woo is not easy, and you’ll need a lot of resources:

Where to Farm Sung Jin-Woo Materials

All required items drop from the Sung Jin-Woo boss located at Fossil Island.

• Spawns every 5 minutes
