Engineer

Classes, Gems, the first chunk, and boss totems for 100 Days on Chunk on Roblox. Prices match the lobby figures published through October 1, 2026, and unknown drops stay blank.

What is Engineer?

Engineer is the only class sold for Robux. You start with an extra Crossbow for base defense, and crafting-level requirements are 50% cheaper, so higher-tier builds unlock sooner. The discount is on the level requirement, not a published 50% off every material. A September 16, 2026 playthrough showed the card at 320 Robux. Later writeups say 399 Robux.

How do you get Engineer?

Buy with Robux in the lobby Classes shop. Confirm the number on the button, then equip Engineer before the next run. Gems do not buy it.

How do you use Engineer?

Equip Engineer when you want the Crossbow at spawn and you plan to push crafting level. Read the lobby price on the day you buy. A Gem class is the substitute if you do not want to spend Robux.

Which class does a new run use?

The class you have equipped in the lobby is the one the next run uses. Unlocking it without equipping it leaves the previous class in the run.
