1. Required Tools

Mechanical Fishing Rod

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.

Worm
Bait

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
Capture Tool

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.

Captured Boss Heart

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

  1. Carry the Rod, Worms and Capture Nets into the Fishing Boss area.
  2. Use the Rod on the green fishing ground. Your normal base catch check is 20%.
  3. A boss becomes eligible after 15 successful catches. Its progressive appearance chance rises until the boss is guaranteed by successful catch 30.
  4. Only bosses whose required Fishing Boss Skill you meet enter the selection pool.
  5. 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.
