The Treasure Anglerfish guards the Saltpeter Desert in Lost Castle 2, and it punishes players who try to outrun it instead of timing their dodges. It has a surprisingly small set of moves, but its large body covers ground fast and its huge mouth closes the gap before you can react. The fight comes down to one habit: watch the jaws, dodge as they snap, and keep yourself behind the boss.
Quick answer: Stay behind the Anglerfish, dodge-roll above or below it the instant its mouth begins to close, and expect a second bite right after the first. When it burrows and the ground shakes, sprint away to dodge the emergence, then punish it during the short rest after its third dive.
Treasure Anglerfish attack patterns
For most of the fight, the Anglerfish only wants to bite you. There are no waves of projectiles to track like the Behemoth fight, but the boss’s speed and reach make its simple moves dangerous. You cannot walk out of range, so the dodge roll and jump are your main tools for survival.
| Attack | How to dodge it |
|---|---|
| Standard bite | Watch for the brief delay between the lurch and the snap. Roll above or below the fish as the mouth starts closing, and brace for a second bite about a second later. |
| Dash bite | The fish swims rapidly across the sand to reach you. Dodge as the jaws begin to shut, then slip behind it since it cannot turn quickly. |
| Underground suction emerge | It dives, shrinks to just its fin, and chases you. When the ground shakes and it stops moving, put as much distance between you as possible before it bursts out. |
| Underground leap | On the second dive it jumps out instead. Stay clear of the large red circle before it lands. |
| Double bite finish | After the third dive it surfaces with two quick bite snaps in a row. Roll through both, then attack during the rest that follows. |
How to beat the Treasure Anglerfish
Rewards for defeating the Treasure Anglerfish
Clearing the fight pays off with crafting materials and unlocks for later runs. You will know the boss is down when the arena clears and the drops appear.
- A chunk of Black Iron Ore
- General loot for your current run
- The Anglerfish Liver
- The boss’s unique armor and weapons, unlocked for future attempts
Defeating it also clears the hidden “Diet Control” achievement for taking down the Treasure Anglerfish in the Saltpeter Desert. If a run keeps ending here, the cause is almost always getting clipped by the second bite or being caught too close during an emergence, so widen the gap before the fish surfaces and you will close the encounter cleanly.
