How to Get and Use Shark Fin in Path of Exile 2

If you’ve been wandering through the Karui Archipelago in Act 4 of Path of Exile 2 and suddenly found a Shark Fin sitting in your inventory, you’re probably wondering: what the hell do I even do with this thing? Don’t worry—you’re not alone. Almost every veteran ARPG player has had that moment of staring at this massive quest item clogging up their stash and thinking it must be some hidden crafting material or a weird weapon.

Here’s the truth: the Shark Fin in Path of Exile 2 is a quest item tied to the side quest Tribal Medicine. You can’t equip it, you can’t sell it, and you can’t stash it away in your hideout. The only way to clear it out is by handing it over to the right NPC. But here’s where things get tricky—the NPC’s location changes depending on your story progression.

In this guide, I’ll walk you through how to get the Shark Fin, where to find Kaimana, and how to make the right choice when you finally trade it in. Along the way, I’ll share a few veteran tips on picking the right reward gem for your build.

Where to Get the Shark Fin in Path of Exile 2

You’ll first come across the Shark Fin when you take on the optional boss called The Great White One. This monster lurks on Whakapanu Island, which you’ll visit during Act 4 of the campaign.

• Location: The boss can be found in the Shark Pit, a sandy arena tucked away at the edges of the island.

• Fight Overview: The Great White One isn’t a story-locked encounter—you can skip it entirely if you want—but defeating it is the only way to get the Shark Fin. Expect lots of knockback, water-based AoE, and adds swarming you in waves.

Once the boss goes down, the Shark Fin automatically drops as a quest item. At that point, the game adds the Tribal Medicine quest to your journal.

Why You Can’t Just Drop the Shark Fin

This is one of those moments that separates new players from seasoned ARPG vets. The Shark Fin is a “sticky” quest item—it’s designed to live in your inventory until you actually finish the quest. You can’t throw it away, stash it in your chest, or trade it to another player.

And trust me, it gets annoying fast. It takes up space, it serves no purpose outside of the quest, and it can feel like dead weight if you’re deep in Act 4 and can’t find Kaimana yet. The only way to ditch it is by turning it in.

Step 1: Track Down Kaimana

Here’s where things get interesting. Kaimana, the NPC you need, doesn’t stay in one place. Her location depends on how far along you are in the Act 4 storyline.

• Early Act 4: If you fought the Great White One early, Kaimana will still be hanging out in the starting settlement on Ngakanu Island. This is the southern island you can sail to after leaving Kingsmarch.

• Later Act 4: If you progressed deeper into the story before fighting the shark, Kaimana relocates to Kingsmarch. You’ll find her on the Karui ship docked opposite Makoru’s ship.

Pro tip: if you can’t seem to give her the Shark Fin on Ngakanu, you might need to push further through Act 4’s quests. After finishing “The Search,” she’ll reliably appear in Kingsmarch.

Step 2: Turn In the Shark Fin

Once you’ve found Kaimana, all you need to do is talk to her. The dialogue option to hand over the Shark Fin will pop up automatically. Completing this step finalizes the Tribal Medicine quest and, finally, clears that oversized shark part out of your bag.

But the real reward here isn’t the freed-up inventory space—it’s the gem you get to choose.

Step 3: Pick Your Reward

Kaimana doesn’t just thank you and send you packing. Instead, she gives you a choice of three different Uncut Gems. Each gem type offers a very different benefit, and picking the right one can have a huge impact on your build.

Here are the options:

1. Uncut Skill Gem (Level 11)

   • Creates a brand-new active skill gem.

   • Best choice if you’re looking to expand your build with a fresh ability.

   • Great for experimenting with playstyles or if you’re still figuring out your main damage source.

2. Uncut Spirit Gem (Level 11)

   • Generates a gem that provides passive, permanent effects like auras or buffs.

   • Perfect if your build is already solid but needs more utility or survivability.

   • Veteran players often lean toward Spirit Gems because of how well they scale in endgame.

3. Uncut Support Gem (Level 4)

   • Creates a gem to enhance an existing skill.

   • This is a lower-level gem compared to the other two, but don’t underestimate it. A powerful support gem can multiply your DPS if it synergizes with your main skill.

Which Gem Should You Choose?

Honestly, this is the part where the answer depends heavily on your build. That said, here are some guidelines from my own playthroughs:

• If you’re still experimenting → Go for the Uncut Skill Gem. It opens new doors and lets you try different damage types or mechanics.

• If your build is locked in → The Uncut Spirit Gem is usually the best long-term investment. Auras and buffs scale into endgame content and can completely reshape how your character plays.

• If your main skill feels strong but clunky → Pick the Uncut Support Gem. Even at level 4, the right support can feel like a major power spike.

Veteran Tips for Tribal Medicine

• Do the boss early if you can. Fighting the Great White One before pushing far into Act 4 makes finding Kaimana easier since she’ll be on Ngakanu.

• Save before you choose. If you’re the type who hates commitment, you can always back up your save before turning in the Shark Fin. That way, you can test each gem and see which feels best.

• Think ahead. Don’t just pick based on your current gear. Ask yourself: what’s going to help me in the long run, especially in maps and endgame?

Why the Shark Fin Quest Matters

At first glance, Tribal Medicine looks like a filler side quest. But in reality, it’s one of those subtle milestones that shows how Path of Exile 2 rewards exploration and decision-making.

The Shark Fin isn’t just about loot—it’s about learning how POE 2 handles quest progression, NPC movement, and reward choice. For players coming from the first game, it’s a reminder that Grinding Gear Games has doubled down on making side content meaningful, not just optional fluff.

Plus, there’s the practical benefit: nobody wants a giant fish part clogging up their bag space.

Final Thoughts

The Shark Fin in Path of Exile 2 is one of those quirky quest items that throws new players off, but once you know how to handle it, the process is simple. Kill the Great White One, track down Kaimana, and choose the gem reward that best fits your build.

My advice? Don’t sleep on Spirit Gems. They can transform your character in ways you won’t appreciate until you’re knee-deep in the endgame grind. But ultimately, the choice should reflect how you like to play. That’s what makes Path of Exile 2 special—you’re never locked into a single right answer.

And if you’re planning to push deeper into the late game, don’t forget that managing your resources—whether it’s gems, gear, or even poe 2 currency—is just as important as your mechanical skill. If you’re looking for reliable ways to keep your stash stocked, sites like G4mmo can be a lifesaver when it comes to keeping your builds moving forward.

So, next time you see that oversized Shark Fin in your bag, don’t panic. You’re just a few steps away from turning it into one of the most useful quest rewards in Act 4.
