- Depth Incremental drill progression centers on balancing damage, speed, and automation upgrades.
- Pickaxe damage first: early runs are limited by how fast you break blocks, so raw damage pays off immediately.
- Automation unlocks (auto-drill, auto-click, repair) turn the game from active clicking into idle income.
- Depth-gated resources mean deeper layers require power upgrades before you can mine them at all.
- Meta progression carries between runs, so prioritize permanent power nodes over temporary boosts.
How the Depth Incremental Drill Works
The drill is the core engine of Depth Incremental: it determines how quickly you break blocks, how deep you can descend, and how many resources you extract per run. Every run follows the same loop — mine blocks, gain resources and experience, spend those resources on upgrades, and push toward harder depth layers that gate progress behind power requirements.
Three stats matter most to the drill:
| Stat | Effect | Priority |
|---|---|---|
| Drill Damage | Breaks blocks faster; required for hard layers | ★★★★★ |
| Mining Speed / Cooldown | Reduces delay between hits | ★★★★ |
| Power | Unlocks depth-gated layers (red/hard zones) | ★★★★★ |
| Light Radius | Reveals surrounding blocks and pickups | ★★★ |
| Experience Gain | Faster level-ups, more frequent rewards | ★★★ |
No amount of drill damage will let you mine through power-gated layers. If a block layer refuses to break, you need a power upgrade from the meta progression tree — not more damage. Stop wasting time clicking and go unlock the next power node.
Early on, the loop is simple: hold to mine, collect coal and stone, and dump everything into drill damage. As runs get longer, the question shifts from "can I break this block" to "which upgrade gives the most value per resource spent" — and that is where prioritization matters.
Drill Upgrade Priority: What to Buy First
Upgrade order makes or breaks a run. Spending resources on the wrong nodes early can leave you unable to push depth before the timer expires.
| Phase | Buy First | Buy Second | Skip Early |
|---|---|---|---|
| Opening (0–2 min) | Drill damage | Repair automation | Cosmetic/utility nodes |
| Mid-run (2–5 min) | Auto-click, auto-drill | Extra seconds per resource | Expensive damage tiers |
| Late run (5+ min) | Additional automatons | Durability, speed | New unlock chains |
| Between runs | Power nodes in meta tree | Experience gain | One-off consumables |
Auto-Click Path
- Removes manual holding entirely
- Frees you to sweep wide areas
- Excellent for thorough mining styles
Burst Drill Path
- Massive short-window damage
- Overheats on cooldown
- Best in story/tutorial runs
Automation Path
- Automatons mine independently
- Break down and need repairs
- Strongest long-term scaling
Mining every resource block on the way down extends your timer (each resource grants bonus seconds). A thorough sweep can stack huge time reserves, letting you clear the entire shaft and bank resources before the run ends. Speed-rushing depth works only when your damage already one-shots blocks.
Step-by-Step Drill Run Strategy
Follow this sequence for consistently deep, resource-rich runs.
Open with Damage
Spend your first resources on drill damage. Early blocks are soft, and every damage tier compounds into faster experience gain and earlier level-ups.
Repair and Deploy Automatons
Automatons break down constantly in the early game. Make repairs your first action every time they fail, then let them descend while you mine adjacent tunnels.
Unlock Auto-Click
Auto-click is one of the highest-value unlocks in the game — it eliminates manual holding and lets you sweep wide arcs alongside your automatons.
Farm Respawning Nodes
Certain resource formations respawn as you mine them. Park on these nodes and mine in sequence for near-infinite income of specific resources during the run.
Push Depth with Power
Once damage and automation are stable, invest meta currency in power upgrades to crack the deeper, gated layers — that is where high-value resources live.
When the shaft bottom is blocked and the timer is long, clear every remaining block instead of idling. Leftover resources convert directly into meta progression currency.
Resource Management and Common Mistakes
Different resources feed different upgrade trees, and scarcity varies dramatically by depth.
| Resource | Used For | Availability |
|---|---|---|
| Coal / Stone | Damage, speed, auto-click, light | Plentiful early, dries up at depth |
| Gold Ore | High-tier unlocks (burst drill, time) | Power-gated, needs level/power to mine |
| Bloodstone / Rare Gems | Meta and advanced upgrades | Sparse — target nodes deliberately |
| Experience | Level-ups, zeppelin-style rewards | Gained from every block mined |
Common mistakes that kill runs:
- Tunnel-visioning straight down while ignoring side resources, then running out of timer fuel.
- Buying time extensions when you have hundreds of seconds banked — buy damage instead.
- Ignoring repairs — broken automatons are dead income.
- Missing level-up pickups — rewards drop at your mining location; grab them before moving on.
Bloodstone-style rare drops are intentionally limited per run. If an advanced upgrade needs them, plan to accumulate across multiple runs rather than expecting to finish it in one.
Run Goals Checklist
Per-Run Essentials:
- Repair all automatons immediately when they break
- Unlock auto-click before investing in damage tiers
- Mine every resource block to stack bonus seconds
- Collect all level-up reward pickups
- Spend leftover resources before the timer ends
- Bank at least one power node in the meta tree
The single biggest long-term lever is the power line in the meta tree. It gates depth, and depth gates every high-value resource. When choosing between a temporary in-run boost and a permanent meta node, take the meta node almost every time.
Depth Incremental Drill FAQ
Q: What is the best first upgrade for the Depth Incremental drill?
Drill damage. It accelerates every part of the loop — faster blocks mean faster experience, more resources, and earlier unlocks. Auto-click comes a close second once you can afford it.
Q: Why can't I mine certain blocks no matter how much damage I have?
Hard layers are gated by power, not damage. You need to unlock the next power tier in the meta progression tree before those blocks become mineable at all.
Q: Is it better to rush depth or clear everything thoroughly?
Thorough mining usually wins. Every resource block grants bonus seconds, so clearing wide stacks a large time reserve. Rushing depth only makes sense when your damage already one-shots everything in your path.
Q: Should I repair automatons or buy new ones first?
Repair first — it is far cheaper than a new automaton, and a broken unit produces nothing. Add extra automatons once your existing fleet stays alive and your income supports the cost.
