Another step you need to take to get a 100% completion run is to interact with all of the NPCs that require your help. Helping every NPC you find can help you in a lot of ways, from earning leaves to obtaining items and weapons that will aid you in your journey.

Be on the lookout for any NPCs with a golden chat bubble on their head since it usually means they'll have a side story ready for you to take.

Gramophones are a type of item that can be used to play tracks inside a tavern, and they can be found everywhere in the world and obtained using different methods.
