Drill to Earth's Core Beginner's Guide – Best Starter Classes, Layer Depths & Drill Upgrades
Drill to Earth's Core is a 30-player co-op descent through twelve named layers. This guide gives you the numbers a beginner actually needs: what each class costs in Cores, how deep every layer runs and what its boss wall hits for, which drill upgrades are worth their Coins, and whether either game pass earns its price. Live stats sit on the hub.

1. Buy the Miner First, Then Save for a Real Role
Two currencies do different jobs, and mixing them up is the classic beginner mistake. Cores are the only currency that buys classes and lobby items; Coins are earned and spent inside a single run. Cores come from achievements, daily quests and the lobby Cores boost, and in-run from chests and boss walls — the wiki puts the boss-wall rate at a flat 10 Cores per layer broken, with chest payouts rising with depth.
Roblox's badge API listed 24 “Unlock the … class” badges for this universe on September 2, 2026. Sixteen have a verifiable price — fifteen from the wiki's class table, plus Executioner from the developers' August 15 patch notes:
- 100 Cores — Miner (Level 1: +50% Pickaxe Damage). Nothing else is remotely this cheap.
- 3,000 Cores — Scout (+20% Movement Speed), Healer (+10% Healing).
- 5,000 Cores — Tank (+100 Health), Gunslinger (+50% Gun Damage), Mechanic (+50% Fuel Contribution), Driller (+50% Drill Power), Bruiser (+50% Melee Damage).
- 10,000 Cores — Demolitionist (+50% Explosive Damage), Reaper (enemies have a 20% chance to drop Soul Orbs that heal 25 HP), Princess, Lucky Looter.
- 30,000 Cores — Goblin King, Bounty Hunter, Pirate, Executioner (starts with a 100-base-damage Executioner Sword and +100% damage to bosses across melee, guns, explosives and pickaxe).
Every class shares one shape: Level 4 is always the Team Bonus, gated behind cumulative depth. Miner unlocks its at 500,000 total depth; Scout and Healer at 3,000,000; the five 5,000-Core classes at 5,000,000; Demolitionist and Reaper at 10,000,000; Bounty Hunter and Executioner at 20,000,000; Goblin King at 30,000,000. A cheap class you finish beats an expensive one you stall on — the whole argument for starting on Miner. Separately, 2,500 Cores rerolls a passive from a class you already own.
The other eight badged classes — Recruit, Racer, Witch, Salvager, Crafter, Nightcrawler, Gunsmith and Priest — carry no price we could verify, so we are not inventing one. Some are barely touched: Salvager had 171 badge holders on September 2, 2026, against 3,680,456 for Miner.
2. Learn the Layer Depths Before You Commit to a Run
The descent is a fixed ladder of twelve layers, each ending in a boss wall, so knowing where the next wall sits tells you whether to push or bank. Depths and wall HP below come from the community wiki's Layers table, cross-checked against the layer-completion badges on Roblox's badge API, which rank in exactly this order.
| Layer | Depth | Boss wall HP | What changes |
|---|---|---|---|
| Grass | 0 – 3,000m | 100 | Goblins only; first Dungeon guaranteed at 3,000m |
| Dirt | 3,000 – 10,000m | 500 | Goblin Brutes; Spider Tunnel and Mineshaft appear |
| Stone | 10,000 – 17,000m | 1,000 | Loot Goblins steal items; Dungeons Level 2 and 3 |
| Clay | 17,000 – 24,000m | 2,000 | Void Clay wall drains the drill's fuel completely |
| Fossil | 24,000 – 31,000m | 4,000 | Spiders join the spawn pool |
| Crystal | 31,000 – 41,000m | 10,000 | Bombo, Bats and Fuel Leeches start spawning |
| Toxic | 41,000 – 51,000m | 25,000 | Toxic mutation; the rest stop is destroyed |
| Radioactive | 51,000 – 61,000m | 50,000 | Toxic mutation continues |
| The Abyss | 61,000 – 72,000m | 100,000 | Mole Man appears; all mutations, higher chance |
| The Void | 72,000 – 84,000m | 200,000 | Void mutation only |
| Glowing Core | from 84,000m | 500,000 | Wolf Bat; its boss wall sits at 100km and pays a Void Crystal |
| Heart of the Earth | from 1,000,000m | 5,000,000 | Every enemy and every mutation, permanently |
Badge counts show how brutal that ladder is. Of the 11,943,722 accounts holding the “Welcome” join badge on September 2, 2026, 7,961,366 cleared Grass, 994,417 finished Crystal, and only 416,939 earned “Reach The Core” — about 3.5% of everyone who pressed play. Past that, 218,688 hit 150,000m and 149,050 hit 200,000m; the Heart of Earth badge, created August 28, 2026, had 200 holders. Trading Post sell prices rise 0.2x every 100km, so depth is also the economy.

3. Spend Coins on Drill Upgrades in Rarity Order
Drill upgrades are bought with Coins during a run and improve the shared machine, not your character. The base prices are 100 Coins (Common), 250 (Rare), 500 (Epic), 1,000 (Legendary) and 10,000 (Mythic) — and each purchase within a rarity permanently raises that rarity's price for the rest of the run by 20, 50, 100, 200 and 10,000 Coins respectively.
That escalation is the whole strategy. Commons stay cheap far longer, so stacking Drill Power (wall damage), Fuel Storage, Drive Speed, Drill Defense, Deadly Drill, Team Health, Sack Storage and Power Drive is the reliable early spend. Mythic is the opposite: Cart Extension costs 10,000 Coins and jumps another 10,000, making it a once-per-run purchase.
Rare holds Power Slam (every 10th hit deals bonus wall damage), Engine Overdrive, Mega Drill, Firepower, Sharpness and Blast Power. Epic holds Power Burst (Burst Mode for the driver), Mounted Gunner, RPM Overclock and Life Steal. Legendary holds Money Drill, Ultra Drill and Health Regen — the three things that end runs are no money, no wall damage and no health, so take whichever your team is short of.
4. Hold the Line at Boss Walls — That Is Where Cores Come From
Ordinary walls appear roughly every 700m to 1km. The boss wall ending each layer is different: highest HP in the layer, flanked by two cave entrances, and the moment the drill damages it the layer sends a wave. Enemies spawn from three fixed positions — both caves and directly behind the drill machine — so a solo player defends three lanes at once.
Two rules from the August 15, 2026 patch change how you fight them. Teleporters are disabled while a boss wall is active, so you cannot retreat to the fortress and wait it out, and players regenerate 1 HP every 12 seconds — slow enough that a Healer or the +100 health pass matters from Toxic down. Skipping a cutscene also needs 75% of votes.
One trap worth memorising: the Clay Layer's boss wall is a Void Clay wall, and arriving at it empties the drill's fuel completely — top up before 24,000m, not after. Every layer crossing drops you at a Rest Stop, and clearing the wall pays the whole team the Cores that fund your next class.
5. Detour Into Structures Instead of Drilling Straight Down
Drilling in a straight line is the slowest way to play: side structures spawn beside the drill machine and hold the chests, ores and gear that gate your progress. The first Dungeon is guaranteed at 3,000m; after that a random structure appears roughly every 7km.
By layer: Dungeons Level 1 in Grass; Spider Tunnel and Mineshaft in Dirt; Dungeons Level 2 and 3 in Stone; Vampire Mansion in Clay, which drops Golden Keys; and Spider's Lair and Goblin's Arena in Crystal, the two hardest on the wiki's scale. A Church appears roughly every 300km and stores equipment so a wipe does not cost the whole run.
From Crystal onward, budget for Bombo: a walking bomb that targets your drill's welded and crafted items before it targets you, disables everything in its blast radius for one minute, and always explodes when defeated — killing it early does not save you. Mounted Gunners are immune. Fuel Leeches start in the same layer, which is where the Mechanic's +50% Fuel Contribution stops being a luxury.
6. Decide Whether the Two Game Passes Are Worth 178 Robux
Exactly two passes are on sale, both read from Roblox's game-pass product-info endpoint by gamePassId on September 2, 2026:
- +5 Sack Storage — 79 Robux (gamePassId 1784326262, created April 3, 2026): five extra sack slots, so you loot longer before unloading.
- +100 Extra Health — 99 Robux (gamePassId 1783880798, created April 3, 2026): +100 max HP, which is the single stat that decides how deep you survive.
A third entry, Skip Card Animations (created August 26, 2026), comes back flagged not for sale with no price, so treat it as staged. If you have seen these passes quoted at 199 and 399 Robux, that is wrong — 2.5x and 4x the live prices. Buy health first: sack space overlaps with the Common Sack Storage upgrade you can buy in-run for 100 Coins, while nothing in the run shop gives a flat +100 HP.
On codes: there is no code redemption system in this game, and the lists published under its name belong to a different title. The full proof, and the standard we hold it to, live on the Drill to Earth's Core codes page and in how we verify codes.
