Path of Exile 2: How to Obtain and Utilize the Shark Fin in the Tribal Medicine Quest
In Path of Exile 2 (PoE 2), Act 4 introduces the Tribal Medicine side quest, which begins upon acquiring the Shark Fin item. This quest offers players a unique opportunity to engage with the game's intricate quest system and earn valuable rewards. Here's a comprehensive guide on how to obtain and use the Shark Fin in PoE 2.
How to Obtain the Shark Fin
To acquire the Shark Fin, players must defeat the Great White One, an optional boss located on Whakapanu Island in Act 4. The battle takes place in the Shark Pit area, a sandy open space near the water's edge. Go near the edge of the pit near the water to trigger the Great White One boss fight. Upon defeating the Great White One, the Shark Fin item will drop, and the Tribal Medicine quest will be added to your journal. 
Completing the Tribal Medicine Quest
After obtaining the Shark Fin, your next objective is to find a use for it. This involves locating Kaimana, a tribal healer who will recognize the Shark Fin and offer you a choice of rewards. Kaimana's location varies depending on your progression in Act 4:
-
Karui Village, Ngakanu: Available if you haven't defeated Benedictus, First Herald.

-
Medicine Circle POI, Ngakanu: Appears after defeating Benedictus.

-
Karui Ship, Kingsmarch: Accessible after completing "The Search" quest.

Upon speaking with Kaimana and handing over the Shark Fin, you will receive one of the following rewards:
-
Spirit Gem
-
Support Gem
-
Skill Gem
Additional Tips
-
Inventory Management: The Shark Fin occupies four inventory slots, so it's advisable to complete this quest promptly to free up space.
-
Exploration: Ensure you've explored the Shark Pit thoroughly, as the Great White One's spawn can be elusive.
-
Quest Progression: The availability of Kaimana depends on your main quest progression, so plan your route accordingly.

Conclusion
The Tribal Medicine quest in PoE 2 offers players an engaging side story and the chance to obtain valuable gems. By defeating the Great White One and assisting Kaimana, you can enhance your character's abilities and continue your journey through Act 4.
