Fishing Boss System
Fish up a boss, capture it inside a Boss Heart and summon it in a private Fishing Boss room.
1. Required Tools

Mechanical Fishing Rod
Use it on the dedicated green ground tile. Its fishing cycle is 2.5 seconds and it has no extra boss-catch bonus.
Obtain: Riona's tool shop.

Worms
Fishing attempts use Worms. A successful catch consumes one; a failed cast has a 10% chance to lose one.
Obtain: Riona, Gold Shop and configured monster drops.

Capture Net
Stand directly beside the Fishing Boss and use one Net on it. The Net is consumed and the boss becomes a captured Boss Heart.
Obtain: Riona, Simple Market and Store packages.

Boss Heart
The Heart stores that boss's exact name and outfit. Its tooltip shows which boss is inside. Use it only inside a Fishing Boss room to summon the stored boss; the Heart is consumed on a successful summon.
2. Fish and Capture the Boss

- Carry the Rod, Worms and Capture Nets into the Fishing Boss area.
- Use the Rod on the green fishing ground. Your normal base catch check is 20%.
- A boss becomes eligible after 15 successful catches. Its progressive appearance chance rises until the boss is guaranteed by successful catch 30.
- Only bosses whose required Fishing Boss Skill you meet enter the selection pool.
- When a boss appears, stand next to it and use a Capture Net immediately. A successful capture creates the Boss Heart and starts a 20-minute boss-catch cooldown.
3. Enter a Fishing Boss Room
Go to the Fishing Boss teleport located inside the Fishing area. Enter one of the dedicated rooms before using the captured Heart.
- The boss rooms require Player Level 200+.
- The Heart cannot summon its boss outside the configured Fishing Boss rooms.
- Use an empty room and make sure a valid tile beside you is available for the boss.

4. Summon and Defeat the Captured Boss

- Use the Boss Heart from your inventory while standing inside the room.
- The server reads the stored boss name, spawns that exact Fishing variant nearby and consumes one Heart.
- Defeat it normally to receive its Fishing Boss reward roll and Battle Pass kill progress when applicable.
