Campfire Upgrade Path Guide – 99 Nights in the Forest

The campfire is the heart of your run. Upgrading it expands your safe zone, unlocks new crafting options, and earns you four Firemaking badges worth a combined 7 stars and 12 Diamonds. This guide breaks down every upgrade level with exact fuel costs and farming tips for each material.

Why Upgrade the Campfire?

Each campfire level provides:
- Larger safe zone radius — The Deer stays further away
- New crafting station unlocks — Taming Flute upgrade (Level 4+), Ammo Furnace
- Firemaking badges — 4 badges total (L3, L4, L5, L6)
- Access to special campfire flames — from Supply Crates via Daily Quests

The campfire is also the only thing keeping The Deer out of your base. A higher-level campfire means more time before the fire risks going out and more of your team fits safely inside the zone.

Level 1 → Level 2

Cost: 6 Logs + 1 Coal + 1–2 Wood

This is the easiest upgrade and should be done on Day 3–4. Coal drops from Bears and is occasionally found in chests. If you have not killed a Bear yet, check the Cultist Stronghold area for any loot Coal.

Tip: Do this upgrade before your first night scouting run. The expanded safe zone radius at Level 2 gives you a bit more room to maneuver if The Deer is nearby.

Level 2 → Level 3 *(Firemaking I badge — 1★, 2D)*

Cost: 11 Logs + 2+ Coal + 2+ Fuel Canisters

Fuel Canisters first appear in Iron and Common Chests. They are not rare — you should have 2+ by Day 5 from normal looting. The 11 Logs is manageable with any axe.

What unlocks: Firemaking I badge. The campfire zone expands further. Start building a log stockpile here — later upgrades are very log-heavy.

Tip: Do not hoard Fuel Canisters — they are plentiful enough that using them for campfire upgrades will not leave you short for the Pyromaniac class or other uses.

Level 3 → Level 4 *(Firemaking II badge — 1.5★, 2D)*

Cost: 50–75+ Logs + 23+ Coal + 9–12+ Fuel Canisters + 30+ Biofuel

This is where the grind starts. 50–75 Logs is a lot of chopping. The Lumberjack class (70D) gives:
- Level 1: 20% bonus log per chop
- Level 2: 25% chance to double sapling drops
- Level 3: 20% chance for 1–2 bonus logs per chop

If you have the Lumberjack class, start it at Level 3 now. Without it, make multiple dedicated chopping sessions.

Coal tip: Bears drop Coal consistently. Alpha Wolves (125 HP) also drop it. If Coal is your bottleneck, run animal hunts rather than more chest looting.

Biofuel tip: Biofuel is harvested from specific plants and crops. Farm Plots (20 Wood + 20 Wood) growing certain crops will yield biofuel. Set up your farm around Day 5–8 so biofuel is accumulating by the time you need it for this upgrade.

Level 4 → Level 5 *(Firemaking III badge — 1.5★, 4D)*

Cost: 70–120+ Logs + 45+ Coal + 19–25+ Fuel Canisters + 4+ Oil Barrels + 30+ Biofuel

Oil Barrels are the new bottleneck here. They appear naturally in the Volcanic Biome (and can be found in Legendary Chests). This is the first upgrade that ties you to biome exploration for materials.

Volcanic Biome strategy:
- The Volcanic Biome has Scorpions (50 HP, 20 damage) and Hellephants (800 HP, 30 damage)
- The Ram (unkillable, 25 damage) patrols here — stay mobile
- Oil Barrels spawn in the Volcanic area at campfire Level 5–6, so start collecting them as soon as you see them

Tip: If you are in a multiplayer server, assign one player to log-chopping duty each day. Getting to Level 5 before Day 50 gives you the most benefit from the expanded zone for the second half of the run.

Level 5 → Level 6 *(Firemaking IV badge — 2★, 4D)*

Cost: 275–350+ Logs + 170+ Coal + 35+ Fuel Canisters + 8+ Oil Barrels + 80+ Biofuel

This is the most resource-intensive single upgrade in the game. 275–350 Logs alone requires many hours of chopping. Here is how to approach it:

Log farming plan:
- Use Lumberjack class at maximum level
- Chop every tree you see — don't skip any
- Build 5–10 Farm Plots growing crops specifically for biofuel
- Run the Volcanic Biome repeatedly for Coal and Oil Barrels

Coal farming: 170 Coal is a serious grind. Bears (6 Morsels, 3–4 Steaks, Bear Pelt, Coal) are the best source. Alpha Wolves also drop some. Budget 20–30 Bear kills for this upgrade alone.

Timeline target: Get to Level 6 by Day 70–80 if possible. The Firemaking IV badge's 4 Diamonds are nice, but the main value is the maximum campfire zone for the final stretch to Day 99.

Campfire Flames

Campfire Flames are cosmetic items obtained from Supply Crates, which drop from completing Daily Quests. You can have up to 3 flames active per session. Each has a passive effect:

Blue Hot is the most universally useful — reducing weather penalties keeps players at camp longer at night rather than retreating inside structures. The Alien and Frog Flames are for players who want more combat and alien/frog loot.

Firemaking Badge Summary

All four badges combined: 6 stars and 12 Diamonds — a strong return on investment for the late-game grind.
