All How to Fish Bosses
Seven bosses gate your trip across five islands. Every fight follows one rule: the white bar under the boss's health is the escape timer — run it out and the boss leaves, costing you another summon bait.

General boss tips
- Stock ammo before summoning. The timer doesn't care about your reload discipline.
- Solo or co-op both work — co-op trivializes most fights if you can get a lobby (see our multiplayer fixes if hosting fails).
- The final boss bare-handed unlocks the Handyman achievement. Save that for a victory lap.
