A class is a lobby purchase. It changes the tools and buffs you have at the moment a run starts. It does not level up inside the chunk, and equipping it in the shop is what makes the next run use it.
Buy it, then equip it
- Enter the lobby and open the Classes shop.
- Select Explorer, Chef, Medic, Lumberjack, Ninja, or Vampire. Explorer is free. The other five spend Gems.
- Engineer is the exception. It spends Robux, not Gems.
- Equip the class before you start. The shop shows the class as unlocked, and the next run applies its starter items and buffs automatically.
Compare the number on the button with the table below. A September 16, 2026 playthrough showed Engineer at 320 Robux. Writeups from September 30 and October 1, 2026 list 399 Robux. Those can both be true of different days. The button in your lobby is the price you pay.
Prices and what they change
| Class | Stars | Cost | Starts with | What changes |
|---|---|---|---|---|
| Explorer | 1 | Free | Wooden Sword, Wooden Pickaxe, Wooden Axe | No extra buff |
| Chef | 2 | 75 Gems | 3 Cooked Meat | Hunger falls 30% slower |
| Medic | 2 | 75 Gems | 2 bandages | Heal 10% faster |
| Lumberjack | 3 | 150 Gems | Iron Axe | Chop 10% faster |
| Ninja | 3 | 150 Gems | Nothing listed | Move 10% faster and a 20% chance to dodge a hit |
| Vampire | 4 | 300 Gems | Nothing listed | Meat only, kills fill a blood bar, full bar sword hit deals 3x damage |
| Engineer | 4 | 399 Robux in the later writeups | Extra Crossbow | Crafting-level requirements are 50% cheaper |
Which failure you are buying off
Match the class to the last run, not to the star count.
- Hunger before the campfire is ready: Chef. The meat is a start, and the slower drain is the part that lasts.
- You win the food check and lose the night to damage: Medic. Two bandages and faster healing do not add damage.
- Trees are the bottleneck for floors, walls, and the next chunk: Lumberjack. The Iron Axe is the early wood skip.
- You get hit while you reposition during zombie waves: Ninja. Speed plus a dodge chance is the best published use of 150 Gems if combat, not wood, is the wall.
- You already fight through the night and can live on meat: Vampire. The 3x sword strike needs a full blood bar, and the diet is a real restriction.
- You want higher crafting levels early and you accept Robux: Engineer. The Crossbow is for base defense, and every crafting-level requirement is cut in half. That discount is about crafting level, not a flat 50% off item costs.
Explorer remains the correct class while you are still learning which of those sentences is yours.
Where the Gems come from
Three published sources pay Gems:
- Badge quests. The quest names and the Gem amounts on each badge were not published.
- Biome crates earned during a run. Crate contents were not itemized.
- The survival summary at the end of a run. One day-100 clear showed a Gem total on that screen. Treat any single total as that run's payout, not as the standard reward.
The Gem calculator subtracts the Gems you have from a price you type. It does not look up your account. Full class pages are under Classes. The editorial order, with the same costs, is on the class tier list.
