From the dispatch lanes
Patch notes, Easter Update recap, Volcano Update, balance passes.
Easter Update - Radio Towers, Rival Rigs, and the +1 Day Multiplier
The Easter Update introduced the Radio Tower infrastructure, Rival Rig tier system, and the +1 Day Multiplier buildable. The most heavily contested intelligence mechanic added to the game since launch.
Volcano Update - Lord of Lava, Magma Staff, and the Magma Chest
The Volcano Update introduced the Volcano Region biome, the Lord of Lava raid boss, and the Magma Staff weapon - the apex crowd-control armament in the game.
Four priorities before you set sail
Bonfire. Harpoon. Smelter. Companion rescue.
I · Bonfire
Level the Bonfire before everything else
The Bonfire is your technological skill tree — gates crafting multipliers and advanced blueprints. Reach Level 2 in the first 72 hours or the survival friction compounds.
Bonfire station →II · Smelter
The Smelter is the mid-game bottleneck
Raw iron ore must be thermally converted into Iron Ingots to upgrade to Bonfire Level 4. Most players misjudge this conversion ratio and stall around Day 40.
Smelter station →III · Radio Tower
The Easter Update changed the meta
Radio Towers reveal Rival Rig coordinates. The +1 Day Multiplier blueprint from cleared rigs is now the most contested item in any 27-player server.
Radio Tower guide →IV · Companion
Rescue the right companions at the right time
Companions operate autonomously — buffs to resource generation, defense against sharks, automation of Smelter and Purifier arrays. The right companion halves your daily ops overhead.

Five apex bosses, ranked by raid-readiness demand.
Lord of Lava
The apex elemental raid boss of the Volcano biome. A 95-level elemental entity rooted inside the active caldera, only summonable after the player sacrifices three Fire Golem bodies in the vent. Lord of Lava gates the Magma Staff - the only …
The Kraken
The defining naval boss and the apex structural threat of the deep ocean. The Kraken does not attack players directly on its first three phases - it attacks the raft's hull grid, threatening to sink the entire base if it isn't inter…
Ghost Pirate Stronghold
A static terrestrial raid located on Cursed Island. The Ghost Pirates operate as swarm intelligence - the sheer number of entities generated during the encounter makes crowd-control weapons near-mandatory. The Magma Staff from the Volcano i…
The Cargo Ship
The apex mobile raid event. The Cargo Ship is not a hostile boss - it is an objective that must be chased, boarded, and captured. Successful capture instantly skips the mid-game processing bottleneck by providing enough Iron Ore and Advance…
Common asks at the dock
Common questions. Full list in the FAQ.
How long is a day in 100 Days At Sea?
A full day-night cycle lasts approximately 4.5 real-world minutes - 3 minutes of daytime gathering and 1.5 minutes of nighttime defence. The full 100-day lifecycle is approximately 7.5 hours of active play, though Bonfire fuel efficiency, Radio Tower intelligence, and +1 Day Multiplier buildables can cut that significantly.
What happens if my Bonfire runs out of fuel?
If the Bonfire reaches zero fuel, health regeneration halts, the map becomes inaccessible, and high-threat entities spawn with 100% probability - frequently inside your own stronghold. Treat the Bonfire fuel economy as the defining survival mechanic of the game.
Can I play solo or do I need a crew?
Solo play is fully viable but expensive in operational overhead. Companions (rescueable NPCs) provide passive buffs and automate low-tier tasks. For raid-tier encounters like the Lord of Lava or Ghost Pirate Stronghold, a crew of 2-3 is strongly recommended.
What is the maximum server size?
27 players per server instance. This is a hard cap set by the developers - it cannot be raised via private servers or matchmaking manipulation.
How do I summon Lord of Lava?
Locate three Fire Golems patrolling the Volcano Region's lower slopes, defeat each one, then physically transport their bodies and throw them into the active caldera. The thermal interaction triggers the eruption phase. After the eruption, descend into the caldera to engage the boss.
What is the drop rate for the Magma Staff?
The Magma Staff is a guaranteed 100% drop from the Magma Chest after defeating Lord of Lava. It is the only source of the weapon in the game. Bring Lava Keys to repair or re-roll the staff's durability.
