• Encounter with NPC : After completing the main plot, you will encounter a mysterious NPC on the edge of the cliff carrying a double-headed sword. This is the key point to unlock the identity of the magic swordsman.
• Check the dialogue : If you stayed at the inn before, try rewinding to the moment you met the NPC. Make sure to talk to the NPC again after defeating the dragon and obtaining relevant materials, and he will appear and unlock the identity of the Demon Swordsman.
• Meiwei Village Clues : If you can't find the NPC, you can go back to the place where you fought the dragon - the seaside of Meiwei Village. The NPC's home is located on a hillside in the distance, so pay attention to the surrounding environment.
• Direct conversation : Once you find the NPC's home, you only need to have a conversation with him to officially unlock the character characteristics of the Dragon Demon Swordsman.
Through these steps, you should be able to successfully unlock the Dragon Demon Swordsman character in Dragon's Dogma 2 and enjoy new challenges and gameplay fun. I wish you all the best on your journey of discovery!
