Mechanic Class Guide — Fuel Contribution, Magnet and Scrap Value

What Mechanic actually does

Mechanic costs 5,000 Cores and it solves the problem nobody talks about: fuel.

Everyone knows drill power ends runs. Fewer players notice that the other failure mode is a dry tank, and the game is built to punish it — the Void Clay Wall Boss at 17,000 m empties your drill’s fuel the moment you arrive. A team that can stretch its coal further survives content that a fuel-blind team wipes on.

You start each run with a Gas Can and Mechanic Armor, and the Magnet arrives at Level 2.

Level by level

Fuel contribution compounds across the team

+50% fuel contribution means every coal you feed the drill is worth half again as much. In a 30-player server that is not a personal buff — it is a team-wide resource multiplier, and it is the reason Mechanic ranks above the pure damage classes.

The practical effect shows up at the two fuel-critical moments:

• The Void Clay Wall Boss at 17,000 m, which drains your tank on arrival. The 100 KM plan recommends carrying 3 to 7 coal or more for exactly this fight — a Mechanic makes that coal go further.
• Long boss fights from the Toxic Layer down, where 25,000 HP walls and up turn fuel into a timer.

The Magnet is a convenience that adds up

Level 2 starts you with a Magnet that pulls loot toward you. It sounds minor and it is not: loot scatters in structures, and the walk between drops is time you are not mining, fighting or fuelling.

In a Mineshaft or a Spider Tunnel, where ore and scrap are spread across the room, the Magnet is the difference between clearing a room and picking at it.

Scrap value doubles at Level 3

Scrap sells for +100% Coins at Level 3. That makes Mechanic a genuine economy class, not just a support one.

Scrap is the most common loot in the game — the drill upgrades guide notes that Little and Large Walls appear every 700 m to 1 km, and structures drop scrap constantly. Doubling its sale price is a steady income floor that does not depend on finding a rare ore.

The comparison with Miner is worth knowing: Miner doubles ore and bar prices, Mechanic doubles scrap prices. Which is better depends on whether your runs produce more ore or more scrap — structure-heavy descents favour Mechanic.

Hitting the requirements

• Level 2: contribute 10,000 Fuel to the drill
• Level 3: sell 25,000 Coins worth of Scrap
• Level 4: 5,000,000 m of career total depth

Both gates are grind tasks that the class is already built to do — you will hit 10,000 fuel just by playing the role, and 25,000 Coins of scrap follows from the doubled sale price.

Where Mechanic fits

Mechanic is a support-economy hybrid, and it is one of the better 5,000-Core buys because it improves the team rather than adding to a damage pool that is already deep. Pair it with Driller for the wall and a fuel class for the tank, and the two biggest run-enders are both covered.
