Path of Exile 2’s Chapter 4 has quite a few side quests, including the cryptic Tribal Medicine, which triggers after looting the Shark Fin. This item drops off the Great White One optional boss on Whakapanu Island. The Shark Pit section of the map looks like it could have a boss, but it doesn’t spawn right away. I recommend walking up to the watery area until you see the shark swim by.
Defeating this powerful foe will make it drop the Shark Fin quest item in Path of Exile 2, but where you need to take it is not exactly clear. All the quest says is “Find a use for the Shark Fin” and nothing more. If you’re stumped by this, you're in the right place. We know exactly where to take the item and all the rewards you can pick from. Special shoutout to Sifrila, someone I met in-game, who guided me to the right location to solve the Tribal Medicine quest.
Where to take the Shark Fin in Path of Exile 2 for the Tribal Medicine quest
When you have the Shark Fin quest item in Path of Exile 2 for Tribal Medicine, take it to Ngakanu Island. It’s the first island directly south of Kingsmarch on your map. However, you may want to wrap up Whakapanu Island since one of the Weapon Pieces you need for your main quest is behind the boss Diamora, Song of the Deep.

Whenever you’re ready, return to Kingsmarch, head to the ship, and sail to Ngakanu Island. You won’t find any fights in the village you land at. Just head over to Kaimana and speak to her. She should have a quest marker over her head.
You’ll wind up giving her the Shark Fin after a brief bit of back-and-forth dialogue, which she will then use in medicines. Although you don’t get a medicine vial, you receive something much better for the Shark Fin in Path of Exile 2. You can choose one of the following rewards:
- Uncut Level 11 Skill Gem
- Uncut Level 11 Spirit Gem
- Uncut Level 4 Support Gem

Frankly, which one to select is up to you; pick based on your needs. I chose the Level 4 Support Gem because there are several Level 11 Skill Gems that I’m running out of space for in my bank. I don’t require more Spirit Gems right now either. It’s certainly a useful reward and won’t take you long to claim it.
