Shark Fin (Tribal Medicine) Quest Guide
Tribal Medicine is an optional Act 4 side quest built around one boss fight and one permanent, one-time reward choice. Here's the full path from finding the boss to picking the right reward for your build.
Step 1 — Get the Shark Fin
The Shark Fin drops from the Great White One, an optional boss on Whakapanu Island (Act 4). Look for the Shark Pit, a sandy open arena near the shoreline — walking to the water's edge triggers the boss to emerge from the sand.
Boss quick notes
- Deals physical damage only — elemental resistances don't matter here
- Weak to Lightning damage specifically
- Sand-swim telegraph is visible as a ripple under the surface — stay mobile rather than tanking it
- Bite damage can one-shot squishy builds around level 51 — movement speed boots make the fight much safer
Step 2 — Find Kaimana
Kaimana's location depends on your Act 4 main quest progress:
| Progress | Kaimana's location |
|---|---|
| Before defeating Benedictus, First Herald | Karui Village, Ngakanu Island |
| After defeating Benedictus, First Herald | Medicine Circle, deep inside Ngakanu Island |
| After completing "The Search" quest | Karui Ship, southern dock of Kingsmarch |
Step 3 — Choose your reward
Kaom's Lesson
+30% increased Armour, Evasion, and Energy Shield.
Best for: mixed defense builds, or anyone unsure of their final endgame defensive layer.
Rakiata's Lesson
15% of Armour also applies to Elemental damage · 12% of Evasion converts to Spell Suppression · 12% faster Energy Shield recharge start.
Best for: pure Armour builds, Energy Shield builds, or anyone committed to one defensive layer already.
Frequently Asked Questions
Is the Shark Fin quest choice permanent?
Yes. As of patch 0.5, Kaom's Lesson and Rakiata's Lesson are a one-time permanent choice — there's no NPC option to swap later, though some players have reported the fin can be re-picked up and the boss refought if you haven't turned it in yet.
Kaom's Lesson or Rakiata's Lesson — which should I pick?
Kaom's Lesson (flat +30% Armour, Evasion, and Energy Shield) is the safer, build-agnostic pick that scales with whatever defenses you already have. Rakiata's Lesson is more specialized — it converts existing defenses into secondary bonuses across damage types — and suits builds already committed to a specific defensive layer, like pure Armour or Energy Shield stacking.
What if Kaimana isn't where I expect her?
Her location is tied to your Act 4 main quest progress, not a bug — she moves from Ngakanu Island to the Karui Ship at Kingsmarch's southern dock as you clear more of the story.
Is this quest mandatory?
No, it's fully optional and doesn't block main story progression — but the permanent defensive bonus is strong enough that most guides recommend not skipping it.
