All Bosses in 100 Days at Sea: HP, Drops & Multipliers
Updated 2026-09-02 · Roblox 100 Days At Sea
The short version: there are seven bosses in 100 Days at Sea, defined by the red health bar at the top of the screen: Snorflord (1,000 HP, pizza oven), the Ancient Squid (2,000 HP, squid laser), the Lord of Lava (2,000 HP, magma staff), the King of the Snow (1,800 HP, ice staff), Greenbeard (2,000 HP, boomstick), the Kraken (a night raid, tentacles only) and The Corruptor (20,000 HP, void slicer). HP scales with player count. Every map has exactly one biome, so you get the lava boss or the snow boss, never both. The Anglerfish has no health bar and cannot be killed; it is a night hazard, not a boss.
Boss summary table
| Boss | Base HP | Where | Weapon in boss chest | Pearls | Day multiplier | Corrupt shard |
|---|---|---|---|---|---|---|
| Snorflord | 1,000 | Snorflord treasure island | Pizza oven (a structure) | Not documented | None documented | No |
| Ancient Squid | 2,000 + tentacles | Main squid island, after all tablets | Squid laser | +10 (Entities page lists +5) | +1 | Yes, once |
| Lord of Lava | 2,000 | Volcano island, fire biome | Magma staff | +5 | +1 | Yes, once |
| King of the Snow (Yeti) | 1,800 | Main penguin island, ice biome | Ice staff | +5 | +1 | Yes, once |
| Greenbeard | 2,000 | Last room of the ghost galleon | Boomstick (first open only) | Not documented | Adds the multiplier to the day count | Yes, repeatable |
| The Kraken | 3+ tentacles, 300-500 HP each | Around base on a kraken night | None (jars of jelly) | Not documented | None | Yes, last tentacle, repeatable |
| The Corruptor | 500 (mini), then 20,000 | Boss room of the corruption dungeon | Void slicer | +5 | +1 per clear | No |
Base HP is what the boss bar shows in a solo game; it rises with player count. The Entities page says the Corruptor gains +5,000 HP per kill; treat that as community-reported, unconfirmed. Kraken tentacle HP is listed as about 500 on the Entities page and 300-500 on the Nights page. Multipliers come from the day count page.
Snorflord
Snorflord is a giant boar with 1,000 base HP on the Snorflord (Giant Porc) treasure island, with no documented multiplier or pearl reward. Killing it spawns a purple chest with a pizza oven, a cooking structure for food. Its damage is not documented yet.
Ancient Squid (squid boss)
Each squid island (lever, food, material) has a task that rewards a gold tablet. Place every tablet in the wall on the main squid island, about 500 m from base; the islands sink and the fight starts.
- Eight purple tentacles (about 150 HP each) appear first. They attack anyone close, so use ranged weapons.
- When the last dies the head surfaces with 2,000 base HP, idles, then spins three times firing an eye laser for about 20 damage that is hard to dodge. Kill the last tentacle at full HP, ideally in the morning.
- If it dives before dying, the tentacles return, but it keeps its reduced HP.
Rewards: +10 pearls for the whole server (the Entities table says 5), +1 day multiplier, one corrupt shard, and a small island holding the squid laser: auto-aim, about 19-20 DPS, overheats after 10.5 s, and surprisingly weak for a boss weapon. Trade-off: solving the lever squid island locks its red levers, an infinite glue farm; keeping the farm means giving up this boss.
Lord of Lava (lava boss)
The Fire Biome is a huge volcano with three tower-like cliffs around it in a triangle; find the lava island by spotting the volcano on the map. If your map has the ice biome instead, there is no lava region at all, since each map has exactly one of the two. Pick a different seed if you want the other one.
To summon it, kill the magma golem on top of each of the three towers, sack the corpses, and drop them onto the magma at the top of the volcano. An eruption cutscene plays and the Lord of Lava spawns inside. There is no fall damage, so jump straight down. It has 2,000 base HP; use ranged weapons, melee is harder.
What to do with the lava king afterwards: open the arena chest for the magma staff (25 damage, tap the screen to drop a zone-damage meteor), then put the corpse in the crafting table for +30 metal. You also get +5 pearls, +1 day multiplier and one corrupt shard. The boss can only be summoned once per map.
King of the Snow (Yeti)
The ice biome boss, formerly called the Yeti, has 1,800 base HP and is summoned on the main penguin island. Collect all 20 penguins from the 7 ice islands and drop them in the circle by the penguin mother. Penguins do not respawn, and their hitbox is slippery, so harpoon them before bagging them.
Rewards: a chest with the ice staff (three ice spikes that auto-fire at any entity for 25 damage, even the Anglerfish), a corpse worth 1 glue, +5 pearls, +1 day multiplier and one corrupt shard.
Greenbeard (ghost galleon boss)
Greenbeard is a large green-skinned pirate with two ghost cutlasses and 2,000 base HP. Ring the galleon bell from the pirate stronghold (10 glue) and the ghost galleon appears about 3 km from base. Clear 8 pirates on deck, take the portal, clear about 20 more, solve the three-crate colour puzzle, and Greenbeard waits in the last room. He is melee only, so any ranged weapon works.
Killing him adds your current day multiplier to the day count at once, without changing the time of day: on day 100 with x10, the counter jumps to 110. He drops a corrupt shard (the wiki lists it as a guaranteed drop; whether it drops on every repeat kill is community-reported, unconfirmed). The green chest gives a boomstick (70 damage, zone damage, one of the strongest weapons) on the first open and occasionally a galleon boat later. The ship sinks 2 min 30 s after the kill and can be summoned again.
The Kraken
The Kraken is a special night event. Starting at 3 tentacles of roughly 300-500 HP each (more and tougher with players and days), purple tentacles rise around the base and slam its centre, or whoever last hit them. Each wipes any structure on its grid tile. Fight one at a time with melee (they hit lightly) or a low-ammo gun like the ray gun. Every tentacle drops a jar of jelly (3 glue) and the last one a corrupt shard. No multiplier, no chest.
The Corruptor
The strongest boss in the game sits in the central room of the corruption dungeon, entered from the cargo ship portal. Clear the loop of puzzle rooms to open the door. A mini Corruptor with about 500 HP dies first, then the full boss appears with 20,000 HP: a flying one-eyed creature with eight eyed tentacles firing lasers.
Shoot from the doorway; most attacks only hit players below it. It sometimes teleports up to the door, so be ready to step back, and it summons jellyfish, so sweep the room after. Boomstick and ray gun are the best picks. You can leave via the entry portal mid-fight to heal. The kill gives +1 day multiplier, +5 pearls and a chest with the void slicer (24 damage, about 168 DPS, 666 unique ammo that cannot be refilled, no auto-aim). The dungeon vanishes 5 minutes later. This is the only repeatable multiplier source.
The Anglerfish (not a boss)
The Anglerfish appears every night and vanishes at morning. It chases players outside the bonfire's limits, bites them, and glitches the screen when close; it can cross islands and fly. It seemingly cannot be slain. To survive, get inside the bonfire limits (it picks another target) or fire an angler flare, which makes it passive for about 10 seconds. A medkit helps if you take a bite.
