The hole is mine best early upgrades determine whether your first two hours feel like a steady climb or a frustrating crawl. With over 300 upgrades spread across four distinct trees, the game gives you plenty of room to optimize, but it also punishes scattered spending. If you dump resources into the wrong branch early, you will feel the drag every time your Mini'Ohs return with less ore than they should. This guide breaks down the exact unlock order, the upgrade requirements that matter most, and a practical tier list so you can spend every Holy Blook with confidence from the moment you start purifying the divine Hole.
Why Early Upgrade Choices Set Your Entire Run
Why the 300+ Upgrade Pool Favors Depth Over Breadth
The launch build ships 300+ upgrades across 4 trees, but the playtest build only contained 200+ upgrades across 2 of 5 Caves—meaning roughly one-third of the final upgrade pool is locked behind later Caves. This directly impacts early routing: the first two Caves contain the highest density of mining-speed and Mini'Ohs-launch upgrades, so dumping early gold into the Power tree yields a faster return than spreading points thin. Since the full game spans 40~ Depths with dangers, the playtest's 2-Cave scope means early-game builds should prioritize upgrades that remain useful past Depth 20, not just the first Cave's gimmicks.
The opening hours of Hole Is Mine are all about momentum, and the upgrade system is the engine that drives it. Every upgrade you purchase multiplies the effectiveness of your mining operation, but the four trees — Power, Mining Speed, Efficiency, and Utility — do not contribute equally at the start. Understanding which branches deliver immediate returns versus which ones only shine after several layers of investment is the difference between reaching Depth 10 comfortably and stalling at Depth 6.
The game's design encourages you to think of upgrades as compounding investments. A single point in Mining Speed might seem trivial, but when it applies to every swing of your pickaxe and every Mini'Oh work order, the cumulative effect becomes massive within 20 minutes. According to the official Hole Is Mine Steam page, the full game features 300+ upgrades across those four trees, and the playtest build already included 200+ upgrades across two of the five Caves. That scale tells you the developer expects you to specialize rather than dabble.
Holy Blook is the primary currency for upgrades, and it flows in steadily once your Mini'Ohs are working efficiently. However, the early game gives you just enough to make roughly a dozen meaningful purchases before the costs start climbing. This scarcity is intentional — it forces you to prioritize. Players who spread their first 20 purchases evenly across all four trees consistently report slower progression than those who commit to one or two branches first, based on community discussions and playtest feedback.
The upgrade unlock system adds another layer of strategy. Not every upgrade is available from the start; many require you to reach specific depths, purify certain amounts of impurity, or upgrade the Village to a particular level. This means your early choices also shape which upgrades become available later, creating a branching path that rewards planning ahead.
| Upgrade Tree | Core Benefit | Early Game Impact | Best Starting Investment |
|---|---|---|---|
| Power | Increases damage per swing | Moderate — helps clear tougher rock | 20-25% of early points |
| Mining Speed | Faster extraction rate | High — compounds with every action | 40-50% of early points |
| Efficiency | More ore per deposit | Very High — multiplies all income | 25-30% of early points |
| Utility | Unlocks new mechanics and QoL | Situational — depends on goals | 5-10% of early points |
The Four Upgrade Trees and What They Actually Control
Before you can pick the hole is mine best early upgrades, you need to understand what each tree offers beyond its one-line description. The Power tree increases your raw damage output, which translates to breaking harder rock types faster. Early on, this feels useful because the first few depth bands contain tougher material that slows down your progress. However, damage upgrades have a diminishing return curve — the first five points feel impactful, but points six through ten add noticeably less value per Holy Blook spent.
The Mining Speed tree is the workhorse of the early game. Every point reduces the time it takes to extract a unit of ore, and because you are constantly mining — both manually and through your Mini'Ohs — this upgrade applies to every single action you take. Community testing suggests that players who prioritize Mining Speed reach Depth 15 roughly 20-30% faster than those who split their points evenly, which is a significant margin in a game that takes about four hours to complete.
Efficiency upgrades are the hidden multiplier that most new players overlook. Instead of making you faster, these upgrades increase the yield you get from each ore deposit. A 10% efficiency boost effectively gives you 10% more income without any additional time investment, which then feeds back into buying more upgrades. The compounding nature of this tree makes it arguably the strongest early-game choice, even though its effects are less visible moment-to-moment.
The Utility tree is the wildcard. It unlocks new mechanics like additional Mini'Oh slots, faster respawn timers, and special abilities that can dramatically change your strategy. However, most Utility upgrades have higher unlock requirements than the other trees, making them poor early investments. You are better off ignoring this tree for the first 30-45 minutes and revisiting it once you have a solid income base.
Power Upgrades: When Raw Damage Matters Most
Power upgrades shine in specific situations rather than as a general-purpose investment. The first few depth bands contain Dense Rock and Crystal Veins that require a minimum damage threshold to break efficiently. If you find yourself swinging four or five times at a single block while your Mini'Ohs struggle beside you, that is a signal to invest a few points into Power.
However, the key insight is that Power upgrades pair exceptionally well with critical strike modifiers found later in the tree. A small investment in base damage multiplies the value of every crit you land, turning a 2x damage proc into a 3x or 4x spike. Players who plan to use heavy-hitting equipment like the Heaxy Axe should prioritize this tree earlier, while those relying on rapid, low-damage tools benefit more from Mining Speed.
Efficiency Upgrades: The Compounding Income Machine
Efficiency is the tree that keeps on giving. Each point adds a flat percentage to your ore yield, and because this applies to every deposit your Mini'Ohs extract, the returns stack multiplicatively with your mining speed. By the time you have invested 10 points into Efficiency, your effective income per minute is roughly 25-30% higher than a player who ignored the tree entirely.
The upgrade requirements for Efficiency nodes are also forgiving in the early game. Most of the first-tier nodes only require a modest amount of Holy Blook and a low Village level, making them accessible within the first 15 minutes of play. This accessibility, combined with their compounding nature, is why many experienced players consider Efficiency the strongest early-game tree in the game.
The Best Early Upgrade Order: A Step-by-Step Unlock Path
| Step | Upgrade Focus | Holy Blook Cost | Why This Order |
|---|---|---|---|
| 1 | Efficiency Tier 1 (3 points) | 150-300 | Immediate income boost compounds from minute one |
| 2 | Mining Speed Tier 1 (3 points) | 150-300 | Faster extraction = more deposits per minute |
| 3 | Efficiency Tier 2 (2 points) | 400-600 | Keeps the income multiplier ahead of costs |
| 4 | Mining Speed Tier 2 (2 points) | 400-600 | Maintains the speed-income balance |
| 5 | Power Tier 1 (2 points) | 300-500 | Enough damage to break early Dense Rock comfortably |
| 6 | Utility Tier 1 (1 point) | 200-400 | Unlocks one QoL mechanic, usually Mini'Oh stamina |
This order works because it front-loads the two trees that generate income, then adds just enough Power to prevent bottlenecks, and finally touches Utility only when you have spare resources. The hole is mine early game upgrades that follow this pattern typically let players reach the second Cave region — the Crystal Caverns — within 45-60 minutes, which is noticeably faster than the average playthrough.
One important note: the exact costs listed above are based on the playtest build and may shift slightly in the full release. According to the launch announcement on Steam, the full game includes 300+ upgrades compared to the playtest's 200+, so the early-game pricing structure might have been adjusted for balance. Always check the current costs in your game before committing to a purchase.
Early Game Upgrade Tier List for 2026
How the 500+ Equipment Combinations Change Your First 30 Minutes
With 11 equipments in the playtest and 500+ combinations at launch, your first Shelly loadout matters more than any single upgrade purchase. Early on, pair a mining-speed equipment with a Mini'Ohs-capacity piece to maximize resource extraction per depth; the 500+ combination ceiling means even common early pieces can create 40-50 viable loadouts. The Infinite Hole mode, unlocked post-prologue, lets you find all equipments you left behind—so don't over-invest in a single combo early. Instead, test 2-3 combinations per Cave to learn which synergize with your current upgrade tree before committing to a final build.
To make your decisions even easier, here is a tier list of the hole is mine best early upgrades based on community testing, playtest feedback, and the official game data. This ranking assumes you are playing the full release version as of August 2026 and focuses strictly on the first two hours of gameplay.
| Tier | Upgrade Name | Tree | Why It Ranks Here |
|---|---|---|---|
| S | Yield Boost I-III | Efficiency | The single best early investment; compounds with everything |
| S | Quick Extraction I-III | Mining Speed | Reduces every action's time cost; universally useful |
| A | Sharpened Tools I-II | Power | Helps break Dense Rock without over-investing |
| A | Mini'Oh Vigor I | Utility | Keeps your minions working longer; strong QoL |
| B | Critical Chance I | Power | Good value but requires base damage to shine |
| B | Stamina Recovery I | Utility | Situational; only matters if you mine manually often |
| C | Village Efficiency I | Utility | Better later when Village costs scale up |
| C | Rare Ore Finder I | Efficiency | Low early value; rare ores appear deeper |
The S-tier upgrades should be your first purchases in every run. Yield Boost and Quick Extraction form the foundation of a fast start, and their effects are felt immediately. The A-tier options fill in the gaps — a couple of points in Sharpened Tools prevents the frustration of slow rock-breaking, while Mini'Oh Vigor keeps your automated workforce productive for longer stretches.
The B-tier upgrades are not bad, but they are timing-dependent. Critical Chance only pays off once you have enough base damage to make crits meaningful, and Stamina Recovery matters more if you prefer manual mining over relying on Mini'Ohs. The C-tier upgrades are the ones to skip in the early game; their benefits are real but only become relevant once you are deeper into the run.
Upgrade Requirements and Unlock Conditions Explained
Understanding the hole is mine upgrade requirements is just as important as knowing which upgrades to buy. Every upgrade has two gates: the Holy Blook cost and a hidden unlock condition. Some upgrades require you to reach a specific depth, others need a certain Village level, and a few are tied to story progression or secret discoveries.
The most common early-game unlock condition is depth-based. For example, the second tier of Efficiency upgrades typically unlocks when you reach Depth 8-10, while the third tier requires Depth 15 or deeper. This means you cannot simply save up and buy everything at once — you must progress through the Hole to unlock the upgrades themselves.
Village level gates are the second most common requirement. As you purify the Hole and complete Village quests, your Village level increases, which unlocks new upgrade tiers across all four trees. The community guide for Village progression explains this system in detail, but the key takeaway is that you should not neglect Village quests — they are the primary way to raise your Village level and unlock better upgrades.
A few upgrades have secret unlock conditions that are not shown in the upgrade menu. Community reports suggest that some Utility upgrades only appear after you discover hidden rooms or interact with specific NPCs in the Village. These are not essential for a fast start, but they add replay value for completionists.
| Unlock Condition | Typical Requirement | Example Upgrade |
|---|---|---|
| Depth-based | Reach Depth 8-15 | Efficiency Tier 2-3 |
| Village Level | Reach Village Level 3-5 | Mining Speed Tier 3 |
| Story Progression | Complete specific quests | Utility Tier 2 |
| Secret Discovery | Find hidden rooms/items | Rare Mini'Oh Abilities |
Common Early Game Upgrade Mistakes to Avoid
Even with a clear plan, it is easy to make mistakes that slow down your run. The most common error is over-investing in Power during the first 30 minutes. While breaking rock faster feels satisfying, the income you lose by not investing in Efficiency and Mining Speed will cost you far more time than the extra damage saves. A good rule of thumb is to keep Power at roughly half the level of your Efficiency and Mining Speed combined.
Another frequent mistake is ignoring Mini'Oh stamina. Your Mini'Ohs are your primary workforce, and when they run out of stamina, your income drops to near zero. Investing one or two points into Mini'Oh Vigor or Stamina Recovery early on keeps your automated miners working longer, which translates directly to more Holy Blook per minute. Players who skip these upgrades often find themselves manually mining for long stretches while their Mini'Ohs sleep.
A third mistake is hoarding Holy Blook instead of spending it. Some players save up for a big-ticket upgrade they saw in a guide, only to realize that the smaller upgrades they skipped would have generated far more income in the meantime. Unless you are within 50-100 Holy Blook of a major unlock, spend what you have on the next affordable upgrade in your priority order.
Finally, neglecting the Village is a subtle but costly error. Village quests and upgrades are not just flavor content — they directly unlock higher-tier upgrades and provide passive bonuses. A quick trip to the Village between mining sessions to complete available quests is one of the best time investments you can make.

Advanced Synergies: Combining Upgrades for Maximum Impact
Once you have the fundamentals down, you can start thinking about synergies between upgrades and equipment. The game features 500+ equipment combinations, according to the official Steam listing, and certain upgrade paths amplify specific equipment loadouts dramatically.
The Mending Crutch equipment, for example, provides sustain by healing your Mini'Ohs over time. This pairs exceptionally well with Efficiency upgrades because your Mini'Ohs stay alive longer, meaning they extract more ore per stamina bar. Players who run the Mending Crutch should prioritize Efficiency over Mining Speed, since the healing effect effectively extends their mining uptime.
Conversely, the Heaxy Axe rewards a Power-heavy build. This equipment deals massive burst damage, and when combined with Critical Chance upgrades, it can one-shot most early-game rock types. If you are using the Heaxy Axe, shift your upgrade priority toward Power and Critical Chance after establishing a baseline in Efficiency and Mining Speed.
The Shelly drilling mechanic also interacts with your upgrade choices. Shelly is your drilling companion, and her effectiveness scales with certain Utility upgrades. Players who want to use Shelly as their primary mining tool should invest in the Utility tree earlier than the general recommendation, since her drill speed and fuel efficiency are governed by that branch.
For a complete breakdown of how the upgrade system interacts with equipment and Mini'Ohs, the upgrade system overview covers the full mechanics in detail, while the Mini'Ohs guide explains how to build the perfect minion squad around your upgrade choices.
Frequently Asked Questions
What is the single best early upgrade in Hole Is Mine?
Yield Boost in the Efficiency tree is the strongest early upgrade because it increases all ore income by a percentage, which compounds with every other upgrade you buy. Even a single point provides a noticeable boost within minutes, and the effect grows exponentially as you add Mining Speed upgrades alongside it.
How many upgrades should I buy before the first Cave boss?
Aim for roughly 15-20 upgrades before attempting the first Cave boss. Your priority should be 5-6 points in Efficiency, 5-6 points in Mining Speed, 3-4 points in Power, and 1-2 points in Utility. This spread gives you enough income, speed, and damage to handle the boss comfortably.
Do upgrade costs increase with each purchase?
Yes, upgrade costs scale with each purchase within the same tier. The first point in an upgrade might cost 50 Holy Blook, but the fifth point could cost 200 or more. This scaling is why diversifying across trees is important — you get more value from spreading points than from maxing a single upgrade.
Can I respec my upgrades if I make a mistake?
The full release does not include a respec option according to the official game information. This makes your early upgrade choices permanent, which is why following a proven priority order is so important. If you are unsure, err on the side of Efficiency and Mining Speed, as they are universally useful.
How do I unlock the third tier of upgrades in each tree?
Third-tier upgrades unlock once you reach Depth 20 and raise your Village to Level 5, but specific trees add extra gates—check each tree's story quest or hidden item requirement. Prioritize depth progression alongside Village quests daily, since mining speed upgrades here compound faster than power boosts for early Mini'Oh efficiency.
