Complete NPC Quest Walkthroughs

1. Test Subjects Quest

Location: Fisherman Island
NPC: Scientist
Requirements:

• 1x Darwin Clownfish (Coral reef areas)
• 1x Dogfish (Deeper ocean waters)
• 1x Barracuda Fish (Tropical waters)

Strategy: Start with the Darwin Clownfish as it’s the most common of the three. Use your basic rod near coral reefs – you should catch one within 10-20 casts. For the Dogfish, head to deeper waters and use luck potions if available. The Barracuda can be tricky as it’s a fast fish; try using a better rod if you have one.

Reward: Luck II Potion – This is incredibly valuable as it permanently increases your chances of catching rare fish, making all future quests easier!

2. Kohana Explorer Quest

Location: Kohana Volcano
NPC: Lava Fisherman
Requirements: Catch volcanic fish without falling into lava

Strategy: This quest tests your positioning skills. The lava areas are dangerous – one wrong step and you’re dead! I recommend approaching the fishing spots from the side rather than directly in front. The Lava Fisherman gives you a free Lava Rod when you first talk to him, which has better luck for volcanic areas.

Pro Tip: Fish from the edge of safe zones and use your camera angle to see exactly where you’re casting. The Lava Rod you get as a reward is perfect for all volcanic fishing activities.

3. Spicy Fish Quest

Location: Kohana
NPC: Volcanic Fisherman
Requirements:

• 20x Lava Butterfly
• 5x Magma Goby
• 1x Lavafin Tuna

Strategy: This is a grind quest, but the Kohana Volcano is the best place for it. The Magma Goby has a 1 in 55 chance and spawns frequently here. Focus on catching Magma Gobys first as they’re the bottleneck, then work on Lava Butterflies (1 in 125 chance).

Time Investment: Expect to spend 1-2 hours here depending on your luck and rod quality.

4. Swimming Narwhals Quest

Location: Kohana
NPC: Narwhal
Requirements:

• Catch 150 fish total
• Catch 1 Narwhal

Strategy: The Narwhal is an Epic rarity fish (1 in 2,000 chance) found in Ocean areas. I recommend fishing in the Ocean near Kohana for this quest. The 150 fish requirement will naturally progress as you hunt for the Narwhal.

Reward: Enchant Stone – Essential for upgrading your rods with special abilities.

5. Mushroom Collector Quest

Location: Ancient Jungle
NPC: Forager Jen
Requirements: Collect 30 mushrooms

Strategy: This is a refreshing break from fishing! The mushrooms spawn around the Ancient Jungle floor, glowing slightly to make them visible. They’re easier to spot at night. Look near trees, rocks, and jungle vegetation.

Pro Tip: Make a circuit around the jungle, checking all the spawn points. Mushrooms respawn every few minutes, so you can complete this quest in 10-15 minutes.

Reward: Mushroom Lantern – Helps you see better in dark areas, perfect for night fishing!

6. Variety Diet Quest

Location: Ancient Jungle
NPC: Forager Jen
Requirements: Catch 12 mutated fish

Strategy: Mutations are special versions of normal fish with different colors, sizes, or patterns. Any mutation counts toward this quest. The best strategy is to fish in areas with high fish density and use luck potions.

Recommended Locations: Fisherman Island or Coral Reefs have good mutation rates. The Mutation I Potion you’ll receive as a reward will make future mutation hunting much easier.

7. Prove Thyself Quest

Location: Coral Reefs
NPC: Sam
Requirements:

• 3x Epic Rarity Fish
• 1x Pink Dolphin

Strategy: This quest requires patience and a good rod. Epic fish have varying rarity (1 in 1,000 to 1 in 5,500 chance). The Pink Dolphin is Legendary rarity (1 in 5,000 chance) and appears in deeper ocean waters.

Best Approach: Use your highest luck rod and potions. Fish in Coral Reefs during events like Bloodmoon for better rates. This quest might take several hours, but the 25,000 coin reward is worth it!

8. We’ll Show Him Quest

Location: Coral Reefs
NPC: Ram
Requirements: Catch 8 big fish

Strategy: “Big fish” typically means Rare rarity or above. This is relatively straightforward compared to Sam’s quest. Focus on Rare fish (1 in 250-750 chance) in Coral Reefs.

Reward: Luck I Potion – Always useful for increasing your catch rates.

9. Lost Treasure Quest

Location: Tropical Grove
NPC: Capt Jack
Requirements: Loot 5 treasure chests

Strategy: Treasure chests spawn randomly on beaches and underwater spots in Tropical Grove. Look for glowing chests near rocks and coral formations. They respawn every 10-15 minutes.

Pro Tip: Make a route covering all beach areas and underwater spots. This quest offers the biggest coin reward (40,000) for relatively easy work!

10. Enchanting Discoveries Quest

Location: Esoteric Depths
NPC: Esoteric Gatekeeper
Requirements: Use an enchant stone 30 times

Strategy: You can enchant and re-enchant the same rod multiple times to complete this quest. Each enchantment counts toward your total, even if you remove it immediately.

Money-Saving Tip: Use your cheapest rod for this quest. Enchant it, remove the enchantment, and repeat. This saves your valuable enchant stones for your main rods.

Reward: Super Enchant Stone – Provides better enchantments than regular stones.

11. Diamond Researchers Quest

Location: Fisherman Island
NPC: Lary
Requirements:

• Own an Element Rod
• Catch a Secret Fish at Coral Reefs
• Catch a Secret Fish at Tropical Grove
• Bring a mutated Gemstone Ruby
• Bring a Lochness Monster
• Catch 1,000 fish with a perfect throw

Strategy: This is the hardest quest in the game and requires serious dedication:

• Element Rod: Purchase or craft this advanced rod
• Secret Fish: Extremely rare (1 in 750,000 to 1 in 2,500,000 chance)
• Mutated Gemstone Ruby: Fish for Ruby in Ocean areas and hope for mutation
• Lochness Monster: Another Secret rarity fish
• Perfect Throws: Practice your timing – aim for the green zone when casting

Time Investment: This quest can take days or even weeks to complete. But the Diamond Rod reward is the strongest rod in the game!
