In 100 Days on Chunk, the Roblox survival game where you craft biome chunks, grow a base, and hold off nightly zombie waves, the class you equip decides how your run starts. Each one hands you tools and buffs the moment you spawn, so the gap between a free loadout and a combat-focused one is wide. Below is where each of the seven classes lands and why.
Quick answer: Ninja and Vampire sit at the top; Explorer, the free starter, sits at the bottom. The full ranking is in the table below.
100 Days on Chunk class tier list
| Tier | Classes |
|---|---|
| S | Ninja, Vampire |
| A | Engineer, Lumberjack |
| B | Chef, Medic |
| C | Explorer |
Placements reflect how much each class speeds up mid- and late-game progression, weighing starting tools, combat value, and survival buffs against cost. This ranking reflects the game as it stands in October 2026.
S-tier: Ninja and Vampire
| Class | Stars | Cost |
|---|---|---|
| Ninja | Triple | 150 Gems |
| Vampire | Quad | 300 Gems |
Ninja leans on survivability. A flat movement boost lets you reposition during zombie waves, and the chance to avoid incoming damage outright means fewer runs end to a single bad hit. That combination carries well into the stretch of a run where enemies hit hardest.
Vampire is the combat pick. It restricts your diet to meat and keeps you topped up through kills, which fits an aggressive playstyle. The payoff is the blood bar, which once full lets you deliver a sword hit that triples your damage. For players who want to fight their way through the night rather than wall it off, nothing else matches it.
A-tier: Engineer and Lumberjack
| Class | Stars | Cost |
|---|---|---|
| Engineer | Quad | 399 Robux |
| Lumberjack | Triple | 150 Gems |
Engineer is the only class bought with Robux rather than Gems. You spawn holding an extra Crossbow for base defense, and every crafting level requirement drops by half. That discount compounds over a run, pulling late-game recipes into reach far earlier than normal.
Lumberjack removes the early wood bottleneck. Starting with an Iron Axe and a faster chop rate gets your base framed and expanded quickly, which matters most in the opening days when materials are tight. It does not scale into late combat the way the S-tier picks do, but the head start is real.
B-tier: Chef and Medic
| Class | Stars | Cost |
|---|---|---|
| Chef | Double | 75 Gems |
| Medic | Double | 75 Gems |
Chef and Medic are the cheapest paid options and the best fit for learning the game. Chef starts you with three extra Cooked Meat and slows hunger drain, easing the early food grind. Medic hands you two spare bandages and speeds up healing. Both keep you alive through the early and mid stages, but neither adds the combat or crafting edge that pushes a run further.
C-tier: Explorer
Explorer is the default class and the only one that costs nothing. It spawns you with a basic set of Wooden Tools: a Wooden Sword, Wooden Pickaxe, and Wooden Axe. That is enough to get a first run going, but it offers no buffs, which is why it ranks at the bottom once better options are unlocked.
Gems come from completing Badge quests and opening biome crates, so the climb from Explorer to the Gem-based classes is steady rather than instant. If you are picking one to chase first, a 150-Gem S-tier class gives the biggest jump in what a fresh run can do.
