You need to complete a quest that will also open a common hub for all NPCs. In Chapter 3, location "Bitter Lake (Northern Shore)" from the fire we stand facing the water and run to the right, there will be a dragon with whom you need to fight. Then you need to teleport to the location "cellar" of the second chapter and talk to the NPC, he will give you the necessary medicine. With the medicine we return to the dragon and he will open the hub. There for the trophy you need to talk to the blacksmith at the end of the location and improve any armor.
