Bosses in 100 Days At Sea are the big combat stops you sail to, defend against, or summon. Some sit on islands, some raid your raft at sea, and some only open after a short unlock chain. Use region, start steps, badge goals, and reward leads to pick the next fight your gear can handle.

Summoned bosses
Planned endgame-style fights you start with map objects. Ancient Squid (Squid Boss) uses Ancient Tablets and is a different encounter from The Kraken sea raid.
Ancient Squid
A tablet-summoned Squid Boss tracked by the Arms of Victory badge. Keep it separate from The Kraken sea raid even though both are large sea monsters.
- Type
- Summoned boss

- Summoned
- Badge
- Arms of Victory
- How to start
- Find and activate the Ancient Tablets on the map, then fight the Squid Boss when the summon completes.
- Reward lead
- Defeating the Squid Boss unlocks the Arms of Victory badge. Squid Laser is associated with Ancient Squid progression and the Ancient Squid class, not proven as a full drop table here.
- Prep notes
- Treat this as a planned endgame-style summon. Bring strong weapons, healing, and ammo or special tools before activating the final tablet steps.

Think of bosses as run checkpoints, not one shared arena. Island fights like Snorflord are on-foot challenges once you find the right landmass. Sea raids such as The Kraken hit the raft itself, so guns, ammo, healing, and a clear retreat path matter more than island parkour. Ghost pirate content mixes a repeatable ship dungeon with a named climax boss, so treat Ghost Galleon and Captain Greenbeard as the same family of progress, not two random sea monsters.
Region chains want a little prep work before the real fight. In the Volcano, you clear three Fire Golems and throw the bodies into the crater to unlock Lord of Lava. In the Ice region, travel and summon setup come before the boss spawn. Ancient Squid is tablet-summoned: you activate Ancient Tablets on the map, then fight the Squid Boss when the summon finishes. That tablet route is not the same encounter as The Kraken, even though both are large sea creatures.
Prep that actually matters
- Bring tested weapons and a healing reserve before any named fight.
- Leave inventory space for chest UI, badge progress notes, or loot leads after a clear.
- Keep a way back to the raft when the arena sits on an island, volcano, or ice stop.
- For raft raids, stock ammo and raft defenses first, then fight tentacles and the main body while protecting your path home.
Soft rewards, hard badges
Reward leads are soft, not full drop tables. Snorflord may drop medkits, and medkits also show up under benches near that spawn. After Lord of Lava, Magma Chest and Magma Staff are the main reward leads, but Magma Staff is also the Fire Mage class starter, so do not treat it as boss-only. Squid Laser is tied to Ancient Squid progression and the Ancient Squid class more than to a proven exclusive loot list.
Public badges are safer goals when loot is fuzzy. Cooking With Golems tracks the volcano unlock. Beat The Heat confirms Lord of Lava. King Of The Snow tracks the Ice Biome boss (community name: Yeti). Arms of Victory tracks the Squid Boss. Third Bell Rung wants Ghost Galleon cleared three times in one run.
Common mistakes
- Mixing up The Kraken and Ancient Squid / Squid Boss. One is a sea raid on your raft; the other is a planned tablet summon.
- Jumping into Lord of Lava before the three Fire Golem bodies open the volcano.
- Treating Ghost Galleon and Captain Greenbeard as unrelated systems instead of linked ghost-ship progress.
- Sailing into Ice or Volcano content with no healing, weak weapons, or no raft retreat plan.
- Reading reward leads as guaranteed exclusive drops.
Sail for practice and medkit leads early, use ghost-ship runs for badge and pirate loot progress, then take volcano, ice, and tablet summons when your weapons and healing can hold a full boss prep.
FAQ
Is The Kraken the same fight as Ancient Squid / Squid Boss?
No. The Kraken is an open-sea raid that attacks your raft, often as night or late-run pressure. Ancient Squid is a tablet-summoned Squid Boss you start by activating Ancient Tablets. Keep them separate even though both are large sea monsters.
How do I unlock Lord of Lava?
In the Volcano region, defeat three Fire Golems and throw their bodies into the volcano crater. That unlocks the deeper arena, then you jump in and fight Lord of Lava. The Cooking With Golems badge tracks the unlock step; Beat The Heat tracks beating Lord of Lava.
Does Lord of Lava always drop Magma Staff?
Treat Magma Staff as a reward lead, not a guaranteed exclusive drop. Magma Chest after the fight is the main lead for Magma Staff, but Magma Staff is also the Fire Mage class starter, so it is not proven as boss-only loot.
How do I get medkits from Snorflord?
Snorflord may drop medkits, and medkits are also reported under benches near the spawn area. Bring inventory space and healing before the island fight, and treat medkits as a soft lead rather than a fixed drop table.
What is the Third Bell Rung badge for?
Third Bell Rung unlocks when you defeat the Ghost Galleon three times in a single run. It tracks the repeatable ghost-ship dungeon, which sits next to Captain Greenbeard in the same ghost-pirate family of content.
Is Yeti the official Ice Biome boss name?
Players often call the Ice Biome boss Yeti. The public badge King Of The Snow only says to defeat the boss in the Ice Biome. Use Yeti as the common name and the badge as the official win condition.
How do I start the Ancient Squid fight?
Find and activate the Ancient Tablets on the map, then fight the Squid Boss when the summon completes. Prep strong weapons, healing, and ammo or special tools before the final tablet steps. Arms of Victory tracks defeating the Squid Boss.
What should I bring to any boss in 100 Days At Sea?
Tested weapons, a healing reserve, inventory space for post-fight rewards or badge progress, and a safe way back to the raft. For sea raids, also stock guns, ammo, and raft defenses so you can fight while keeping a retreat path open.
