Bonfire Levels, Sawmills, and Raft Stations

Bonfire level unlocks crafting. Use the reported Sawmill, Magnet, and turret costs only after the craft menu agrees.

Bonfire Levels, Sawmills, and Raft Stations

Bonfire level unlocks crafting. Use the reported Sawmill, Magnet, and turret costs only after the craft menu agrees.

Bonfire levels are the craft gate

Official badges track Bonfire 1 through 7 as reaching that level. Bonfire 8 is different: burn 1,500 items in a single session. Bonfire 9 is reaching max bonfire level with 4 or more people. Bonfire Master is max bonfire before day 3.

An 8 August 2026 crafting tutorial describes seven craft tiers unlocked by Bonfire level. In that explanation, Bonfire level 5 opens recipes through tier 5, and level 7 opens the full menu. A missing recipe can be a Bonfire lock rather than a bug. Check the craft table on your raft.

Materials those guides name

The same tutorial says recipes use wood, metal, and glue. Wood comes from floating wooden debris. Metal comes from floating metal. Glue comes from defeated pirate enemies. Other raft notes use the name Green Gum for a material processed from Ghost Pirate bodies at the crafting machine. Treat those as two reported names until the craft menu shows one ingredient. Do not assume they stack.

Reported station costs

Station Reported requirement What it is for
Sawmill Bonfire 3, 10 Wood + 2 Metal Repeatable planks, 3 per use
Crab Trap After Sawmill; read the menu Passive food
Map Radar After food is stable; read the menu Island marks
Magnet Bonfire 4, 30 Metal + 10 Wood Passive metal
Auto Turret 150 Doubloons at the Travelling Merchant Night defense
Radio Placed after Magnet in beginner routes Marks survivors; read the menu for cost
Cooking pot On the raft First chowder awards We Cookin

These costs are community reports from July 2026, not a patch note. If the preview disagrees, trust the preview.

Fuel versus floors

Keep a wood reserve for the Bonfire. Spending every plank on floors leaves the raft dark. Player comments on March and June 2026 walkthroughs say the day does not advance to night unless wood is put on the fire. That is player-reported, not an official rule, and it may have changed. Test it on a run you can afford to stall, and do not rely on it once a raid timer is already active.

A stable raft

A stable early raft has a fed Bonfire, plank income, a food station, storage you can reach without swimming, and a planned return. Walls and guns matter after that, not before the fire stays lit.

FAQ

Frequently Asked Questions

What is the goal in 100 Days at Sea?

Survive 100 in-game days in the Bermuda Triangle. You hook resources with a harpoon, build a raft, visit islands, and fight the threats named on the official badges.

Is this the same game as 99 Nights in the Forest?

No. 100 Days at Sea is made by Stranded Devs. Its description credits 99 Nights in the Forest, by Grandma's Favorite Games, as the inspiration. Codes from one game do not redeem in the other.

Which codes are worth trying?

Join a server, open CODES in the top-left, type the string exactly, and press SUBMIT. CORAL and SPOOKY are the two codes public trackers still treated as working on 10 November 2026. CORAL's Pearl amount is listed as 20 by most of those trackers and 40 by Destructoid.

What should I build first?

Feed the Bonfire to level 3, then craft Sawmills. Community guides from July 2026 put the Sawmill cost at 10 Wood and 2 Metal and tell you to build at least two. Crab Trap and Map Radar come next. Confirm every cost in the craft menu.

What is the difference between Pearls and Doubloons?

Pearls buy permanent classes and companion chests. Doubloons are the in-run merchant currency. A September 2026 developer note, reported on 10 November 2026, says Doubloons now save between runs and pay for companion upgrades.
