Bosses in Haze Seas fall into two groups. Island Bosses sit on specific islands and hand out Money, EXP, Bounty, and accessory drops on a fast timer, while Super Bosses are high-level fights that gate the rarest weapons, titles, and materials behind summon items and cooldowns. Knowing where each one spawns, what it drops, and how to trigger it is the difference between a clean farm and wasted travel time.
Quick answer: Island Bosses respawn 30 seconds after defeat and can be farmed solo for accessories. Super Bosses have long respawn timers or require summon items, and in a party you must deal at least 20% of the boss’s total HP to receive any rewards.
How boss rewards and respawns work
Island Bosses come back 30 seconds after they die, so they are the reliable source for accessories and steady EXP. Super Bosses either run on a fixed respawn clock (60 to 120 minutes depending on the boss) or must be summoned with a specific item before they appear at all.
The 20% damage rule only matters when you fight alongside other players. If your damage share on a Super Boss falls below one-fifth of its total health, you walk away with nothing, so avoid tagging a boss that a stronger player is already melting.
Sea 1 Island Bosses: locations and drops
These bosses cover the full early and mid progression path across the first sea. Every one respawns 30 seconds after defeat and always gives Money, EXP, and Bounty on top of the listed drops.
| Boss | Spawn Location | Notable Drop |
|---|---|---|
| Bandit Boss | Starter Island | Eyepatch (40%) |
| Clown Boss | Clown Island | Clown Nose (30%) |
| Shark Boss | Shark Park | Shark Blade (Weapon) |
| Bomb Boss | Desert Ruins | Money, EXP, Bounty only |
| Krieg Boss | Sea Restaurant | Gold Pauldrons |
| Tashi Boss | Logue City | Glasses (50%) |

| Minotaur Boss | Three Islands | Oversized Helmet (5%) |
| Ice Admiral | Marine HQ | Sleeping Mask (5%), Tremor Key (5%) |

Note: The Ice Admiral and Warden are worth prioritizing because they drop the Tremor Key and the Match, the summon items you need for two of the Sea 1 Super Bosses.
Sea 2 Island Bosses: locations and drops
The second sea adds a fresh set of Island Bosses, and several of them exist mainly to drop the orbs and fragments that unlock Sea 2 Super Bosses. All respawn 30 seconds after defeat.

|---|---|---|
| Mammoth Boss | Udon Prison | Money, EXP, Bounty only |
| 3SS Boss | Snowy Graveyard | Green Cloak (5%) |

Sea 1 Super Bosses and how to summon them
Super Bosses in the first sea range from a simple hourly spawn to multi-step summon chains. Their drop tables include weapons and rare accessories you cannot get anywhere else.
| Boss (Level) | Location and Spawn | Notable Drops |
|---|---|---|
| Dual Swordsman (500) | Logue City, spawns every 60 minutes | Book (50%), Green Bandana, Gems |
| Mace Boss (700) | Cave behind Marine Base Town, drop a Lava Ore into the cauldron | Mace V1, Coded Mask |
| Tremor Girl (1,000) | Marine Base Town, use the Tremor Key on the Whitebeard-marked gate | Bisento V2 (needs Bisento V1), White Orb |
| Fire Fist (1,400) | Tall Woods, light the campfire and place four pearls on the totems | Flame Fruit (1%), Pearl Necklace |
| Sea Beast | Rocky Pillars, respawns every 30 to 120 minutes | Sea Beast Hammer V1 (50%), Sea Beast Core, Beast Slayer title |
Summoning Fire Fist step by step
For the Mace Boss, the Lava Ore comes from the Marine Captain in Marine Base Town at a 5% rate, and the Lava Key that opens the gate is looted from a table at Marine Base spawn. Tremor Girl needs the Tremor Key, which the Ice Admiral drops at 5%.
Sea 2 Super Bosses and how to summon them
The second sea holds the toughest fights in the game, and most of them require a summon item or a gamepass rather than waiting on a timer.
| Boss (Level) | Location and Spawn | Notable Drops |
|---|---|---|
| Enma Boss (2,500) | Flower Capital, respawns every 60 minutes | Enma Sword (10%) |
| Dough Boss (2,000) | Mirror World, summoned with a Mirror Fragment and 10 doughnuts for 50 Gems; respawns every 120 minutes | Dough Trident (50%), Dough Scarf (10%) |
| Dragon Boss | Dragon Island, place the Dragon Orb on the altar at the top | Horns (10%), Drums of Liberation (100% with Gum Fruit) |
| Darkblade V2 | Foggy Castle, needs the Darkblade Gamepass and the Upgrader NPC quest; respawns every 120 minutes | Night Hat (10%), Night Necklace (0.1%), Darkblade V2 weapon |
| Sea Beast | Deep Seas in Sea 2, respawns every 20 to 60 minutes | Sea Beast Hammer V2 (3.5%), Sea Beast Heart (25%) |

Sea Beast farming across both seas
The Sea Beast is the roaming Super Boss and the source of the Sea Beast Hammer weapons and crafting materials. In Sea 1 it appears at the Rocky Pillars east of Starter Town and respawns every 30 to 120 minutes, dropping the Sea Beast Hammer V1 at 50% along with the Sea Beast Core.
The Sea 2 version prowls the Deep Seas, respawns faster at 20 to 60 minutes, and drops the Sea Beast Hammer V2 at 3.5% plus the Sea Beast Heart at 25%. Both versions award the Beast Slayer title. You know a kill counted when the reward pop-up appears and the drop lands in your inventory, so confirm you cleared the 20% damage threshold before the fight ends.
Sea 3 has not launched yet, so no third-sea bosses, locations, or drops are confirmed. Until it arrives, the two seas above cover every boss you can currently fight, and the summon chains for Fire Fist, Dough Boss, Dragon Boss, and Darkblade V2 are the main gates between you and the rarest weapons in the game.
