🎣 How Fishing Works

🛠️ Unlocking Fishing

1. Defeat Glurch or Ghom (first two bosses)
2. Collect Fibre from grass plants
3. Craft a Basic Fishing Rod at the Workbench (8 Fibre + 6 Wood)
4. Find any water pool — press and hold left-click to cast, release when the bobber splashes!

📈 Fishing Skill

• Level up by catching fish
• Higher level = better catch quality + rare fish chances
• Skill rewards: faster casting, less reel time, rare fish detection

⏰ Time & Location

• Fishing takes real time — no day/night cycle
• Different biomes = different fish pools
• Deeper/larger water pools = better fish
• Fish Traps (crafted later) provide passive fish income

Sunken Sea (deep)	Glow Tuna (65g)	~130g
Azeos' Wilderness	Storm Bass (42g)	~84g
Larva Biome	Glowing Bass (45g)	~90g
Dirt Biome	Crystal Fish (25g)	~50g

Tip: Place 5+ traps in the Sunken Sea for maximum passive income. Check them every 20-30 minutes.

🪤 Fish Trap Guide

Crafting Recipes

Trap Type	Materials	Catch Rate	Notes
Basic Fish Trap	25 Fibre + 12 Wood	Low	Crafted at Workbench
Sturdy Fish Trap	20 Fibre + 8 Iron Bar	Medium	Crafted at Iron Anvil
Advanced Fish Trap	15 Fibre + 6 Galaxite Bar	High	Faster collection

Placement Tips

1. Deep water produces better fish than shallow puddles
2. Large water bodies attract rarer fish
3. Place traps away from each other (cannibalize catch rates)
4. Check traps every 20-30 minutes — they stop catching when full
5. The Sunken Sea has the best trap ROI

💡 Pro Tips

1. Upgrade your rod first — a better rod pays for itself in rare fish
2. Cook your fish — many fish are worth 2-3x more as cooked dishes
3. Fish traps are OP — 5 traps generate more gold than most crops
4. The Sunken Sea is the best fishing zone — highest value fish + Glow Tuna for breathing buff
5. Legendary fish require high fishing skill + upgraded rod — save them for the museum!
6. Sell duplicates — you only need one of each fish for museum/achievement
7. Fish during exploration — every biome has unique fish, so fish as you explore
