The Academy sits in a circle on the lobby floor. Step in to swap to a class you own or to buy one with Cores. The priced table has 26 classes in five tiers. Every class in a tier costs the same.
| Tier | Cost each | Classes | Whole tier |
|---|---|---|---|
| 1 | 100 | Miner, Recruit | 200 |
| 2 | 3,000 | Scout, Healer, Mechanic, Racer, Witch | 15,000 |
| 3 | 5,000 | Driller, Tank, Gunslinger, Bruiser | 20,000 |
| 4 | 10,000 | Demolitionist, Princess, Crafter, Reaper, Lucky Looter, Nightcrawler, Salvager | 70,000 |
| 5 | 30,000 | Goblin King, Gunsmith, Bounty Hunter, Pirate, Prospector, Samurai, Executioner, Priest | 240,000 |
The full set is 345,200 Cores. Miner can be free on the first join, which is one of two free choices. The second free name is not stated in that note.
Levels
You start the run with that class's gear and its level 1 perk. Three more perks unlock when you meet that class's requirements, so the September 2026 tables describe four levels. Requirements differ by class and are not one shared depth. A 10 October 2026 note on Prospector adds a level 4 of +100% Mineshaft spawn chance, requiring 10,000,000 m total depth, and a level 5 that starts you with a Gem Refinery and gives gem veins a 5% chance to drop 10 gems. Other classes are not confirmed to have a fifth level.
Once you own two or more classes, 2,500 Cores rolls a random passive from another class you own onto the one you are playing.
A September 2026 class-shop walkthrough says the shop restocks every 12 hours and that tier 4 and tier 5 classes appear less often. That restock rule is not in the Academy price table. If a class you can afford is missing, check again later before assuming it was removed.
Classes with badges and no price
The 19 October 2026 badge listing includes unlock badges that are not in the 26-class price table:
| Badge | Awards on that listing | What is known |
|---|---|---|
| Mercenary | 56,521 | Used for a full 0 to 100 km run in an 8 October 2026 playthrough. Price unpublished. |
| Vampire | 41,218 | This is the class badge. A separate Vampire badge has millions of awards and tracks the enemy. |
| Jack-o'-Lantern | 1,361 | Listing touched about three days before 19 October 2026. Price and perks unpublished. |
| Engineer | 598 | Described as added on 1 October 2026. Price and perks unpublished. |
Shopkeeper has a badge with 3,112,121 awards. That volume fits an easy activity, not a 30,000 Core class. It is not listed here as an Academy class.
How to choose
Match the buy to the problem you are failing.
- Walls too slow: Driller, then RPM Overclock and Drill Power.
- Not enough coins for cards: Lucky Looter, Salvager, Pirate, or Prospector.
- Dying to bosses: Executioner, or Priest if the party needs healing.
- Guns or melee already feel good: Gunslinger or Bruiser at 5,000, Gunsmith or Samurai at 30,000.
- Explosives, including Stone enemies: Demolitionist.
The letter ranks on the tier list are one 25 September 2026 board. They are not an official order, and they rate Driller lower than the 100 km guides do.
