In 100 Days on Chunk, your class changes what you bring into a survival run and which part of the early game gets easier. Explorer gives you a free set of wooden tools, while the paid options focus on food, healing, faster chopping, movement, combat, or crafting support.
Here's how to unlock a class in the lobby and compare all seven listed options without confusing Gems with Robux.
How to Unlock Classes in 100 Days on Chunk
Classes are unlocked from the shop in the lobby. Choose a class, spend the currency shown for it, and equip it before starting a run so its starter items or ability can apply during gameplay.

- Enter the lobby and visit the Classes shop.
- Select Explorer, Chef, Medic, Lumberjack, Ninja, or Vampire. Explorer is free, while the other five use the listed Gem price below.
- If you want Engineer, purchase it for 399 Robux instead of Gems.
- Equip the class before you begin your run.
If you need more Gems, complete Badge quests or open biome crates. Check the shop's displayed price before buying so you know how many Gems to target.
All Classes in 100 Days on Chunk
The seven classes range from a free one-star tool set to four-star options with specialized benefits. The prices and perks below can change as the live Roblox experience updates, so compare them with the lobby shop before you spend currency.
| Class | Star tier | Cost | Starts with | Ability or benefit |
|---|---|---|---|---|
| Explorer | 1 star | Free | Wooden Sword, Wooden Pickaxe, Wooden Axe | Basic wooden-tool start |
| Chef | 2 stars | 75 Gems | 3 extra Cooked Meat | Hunger decreases 30% slower |
| Medic | 2 stars | 75 Gems | 2 extra bandages | Heals 10% faster |
| Lumberjack | 3 stars | 150 Gems | Iron Axe | Chops 10% faster |
| Ninja | 3 stars | 150 Gems | No starter item listed | Runs 10% faster and has a 20% chance to dodge any hit |
| Vampire | 4 stars | 300 Gems | No starter item listed | Eats only meat, feeds on kills, and can unleash a 3x-damage sword strike with a full blood bar |
| Engineer | 4 stars | 399 Robux | Extra Crossbow | Crafting-level requirements are 50% cheaper |
Explorer
Explorer is the no-cost starting point. The Wooden Sword, Wooden Pickaxe, and Wooden Axe give you a basic spread of tools immediately, making this the straightforward choice when you want to try a run without saving Gems or spending Robux.
Chef
Chef is built around food management. You start with three extra Cooked Meat, and your hunger decreases 30% slower, so this class fits a run where keeping food available is your main early concern.
Medic
Medic gives you two extra bandages and lets you heal 10% faster. Pick it when a healing-focused start is more useful to you than an extra weapon or gathering tool.
Lumberjack
Lumberjack starts with an Iron Axe and chops 10% faster. That combination makes it the resource-gathering choice among the Gem classes when you want to spend less time turning nearby trees into the materials for your base.
Ninja
Ninja improves movement and evasion rather than giving you a listed starter item. You run 10% faster and have a 20% chance to dodge any hit, which suits a mobile playstyle.
Vampire
Vampire is the combat-focused option in the listed Gem roster, but it comes with a food restriction: you eat only meat and feed on kills. Filling the blood bar lets you unleash a sword strike that deals 3x damage, so this class makes the most sense if you're comfortable building your run around kills and meat.
Engineer
Engineer costs 399 Robux, not Gems. It starts you with an extra Crossbow for defending your base, and its crafting-level requirements are 50% cheaper. Choose it only if that ranged start and crafting discount match what you want from the run and the shop still shows the price you expect.
Which 100 Days on Chunk Class Should You Choose?
No single class is the right fit for every run. Match the listed benefit to the part of a run you want to make easier:
- Choose Explorer for a free baseline of wooden tools.
- Choose Chef if extra food and slower hunger loss are your priority.
- Choose Medic if you want extra bandages and faster healing.
- Choose Lumberjack if faster chopping and an Iron Axe help you gather base materials.
- Choose Ninja if faster movement and a chance to dodge hits matter most.
- Choose Vampire if you want the combat-focused blood-bar attack and can manage its meat-only rule.
- Choose Engineer if you're willing to spend Robux for an extra Crossbow and cheaper crafting-level requirements.
These are benefit-based matches, not a universal ranking. Before starting your next run, return to the lobby's Class Shop, confirm the displayed price and perk, and equip the option that matches your goal.
