Every hole is mine mini'ohs player hits the same wall around Depth 10: their little miners fall asleep mid-run, production stalls, and the Village stops growing. Understanding how Mini'Ohs work transforms that frustration into steady progress, because these creatures are the engine behind every impurity you extract and every upgrade you unlock. This guide breaks down the core mechanics, care routines, and role assignments that separate thriving Holes from abandoned ones.
The official Hole Is Mine Steam page describes the game as an incremental adventure about purifying a divine Hole, where you launch Mini'Ohs to mine for you while managing their needs. That management layer is deeper than most players expect, and getting it right early saves hours of wasted drilling.
Understanding All Mini'Ohs Types and Their Base Roles
Every Mini'Oh you encounter belongs to one of several archetypes, and knowing the full roster helps you plan your Village composition from the first hour. The game currently features a diverse set of creatures, each with distinct mining speeds, stamina pools, and special quirks that affect how you deploy them across the 40 available Depths.
Core Miner Archetypes
The foundation of any mining operation rests on three primary types that you will encounter most frequently during early exploration. Each brings a different balance of speed, endurance, and resource preference that shapes your early strategy.
| Mini'Oh Type | Mining Speed | Stamina Pool | Special Trait | Best Depth Range |
|---|---|---|---|---|
| Pebble Puff | Fast | Low | High crit chance on soft rock | 1-10 |
| Granite Grub | Medium | High | Reduced fatigue buildup | 5-20 |
| Crystal Wisp | Slow | Medium | Bonus yield on gem nodes | 15-30 |
| Ember Sprite | Very Fast | Very Low | Ignites nearby impurities | 20-35 |
| Deep Dweller | Medium | Very High | Immune to dark zone penalties | 30-40 |
The Pebble Puff excels in the early game because its fast mining cycles generate quick resources, though you will need to rotate it frequently to prevent exhaustion. Granite Grub becomes valuable around Depth 5 when longer expeditions start taxing your crew, since its reduced fatigue buildup lets it stay awake for extended shifts. Crystal Wisp feels underwhelming at first, but its bonus yield on gem nodes makes it essential once you reach the crystal-heavy strata between Depths 15 and 30.
Specialized Utility Mini'Ohs
Beyond the core miners, exploration can reveal rarer creatures with unique utility that changes how you approach certain challenges. The Ember Sprite ignites nearby impurities, which accelerates extraction in rock-heavy zones but demands constant supervision because its stamina drains rapidly. Deep Dweller thrives in the dark zones below Depth 30, where other Mini'Ohs suffer significant penalties to both speed and stamina recovery.
According to community reports from the Steam forums, the Deep Dweller becomes the backbone of late-game operations because it can work continuously in areas where standard miners would collapse from exhaustion. Players who rush to unlock this type early through targeted exploration report smoother transitions through the mid-game difficulty spike around Depth 25, when impurity density increases dramatically.
How to Get Mini'Ohs Through Exploration and Cloning
Finding new Mini'Ohs requires active exploration rather than passive waiting, because the game ties creature discovery to your drilling progress and specific actions inside the Hole. The official changelog for the Next Fest prologue confirmed that you can find Mini'Ohs while exploring, which means every descent with Shelly carries the potential for a new crew member.
Discovery Methods That Work
| Method | Success Rate | Time Investment | Requirements |
|---|---|---|---|
| Deep exploration with Shelly | High | 10-15 min per run | Unlocked Shelly, Depth 5+ |
| Breaking hidden rock clusters | Medium | Varies | Pickaxe upgrades |
| Completing incursion events | Very High | 20-30 min | Incursion unlocked |
| Trading at Village events | Low | 5-10 min | Village level 3+ |
The most reliable way to get new Mini'Ohs involves taking Shelly on dedicated exploration runs rather than focusing purely on extraction. Hidden rock clusters often contain dormant creatures that wake when you break through, so investing in pickaxe upgrades pays double dividends by unlocking both new areas and new crew members.
The Cloning Mechanic
A particularly powerful discovery from the prologue changelog involves a new item that allows you to clone Mini'Ohs during incursions. This changes the math on rare types significantly, because finding one Deep Dweller no longer means waiting for another random encounter. Community testing suggests that cloning consumes a consumable item and requires the target Mini'Oh to be awake and healthy, which ties directly into your care routines.
Players report that cloning works best on utility types like Ember Sprite and Deep Dweller rather than common miners, since you will naturally accumulate plenty of Pebble Puffs through standard exploration. The item appears during incursion events, so prioritizing those events when they appear on your map accelerates your crew growth substantially.
Essential Mini'Oh Care Routines for Maximum Output
Keeping your Mini'Ohs awake and productive requires understanding their needs, because a sleeping minion produces nothing and wastes your Village resources. The care system operates on several interconnected mechanics that reward consistent attention rather than occasional intervention.
Sleep and Stamina Management
Every Mini'Oh has a stamina bar that depletes while mining and recovers while resting. The key insight from community testing is that stamina recovery accelerates significantly when Mini'Ohs are placed in designated rest zones near the Village rather than left at the mining site. Building rest structures early gives you a compounding advantage that pays off across every subsequent expedition.
| Care Action | Stamina Restored | Time Required | Best Timing |
|---|---|---|---|
| Rest zone placement | 30% per hour | Passive | Overnight |
| Feeding treats | 50% instantly | 2 seconds | Before long shifts |
| Friendship Wool use | 100% + buff | Instant | Emergency situations |
| Rotation between shifts | 40% per cycle | 5 minutes | Continuous operations |
The Friendship Wool item mentioned in the prologue changelog provides an instant full stamina restore plus a temporary buff, making it the most powerful care tool available. However, its rarity means you should save it for emergencies like incursion events where maximum output matters most.
Feeding and Happiness Systems
Mini'Ohs have a happiness meter that affects their mining efficiency, and feeding them appropriate treats keeps this meter high. Each type prefers different foods, and matching preferences grants a 15% efficiency bonus according to player testing. The Heaxy Axe equipment item also appears to interact with the care system, though the exact mechanics remain under investigation by the community.
A practical routine that works well involves checking your Mini'Ohs between every major drilling push. Wake any sleepers, feed treats to anyone below 70% happiness, and rotate exhausted miners into rest zones while fresh ones take over. This cycle takes about two minutes and maintains near-peak efficiency across your entire crew.
Best Mini'Ohs for Different Depths and Situations
Choosing the right Mini'Oh for each situation matters more than simply fielding your highest-level creatures, because the depth-based penalties and resource types vary dramatically. The best mini'ohs for early game differ substantially from what you want in the deep zones.
Depth-Based Recommendations
| Depth Range | Primary Resource | Recommended Mini'Oh | Why It Works |
|---|---|---|---|
| 1-10 | Soft rock, basic impurities | Pebble Puff | Fast cycles, high crit rate |
| 11-20 | Granite, iron deposits | Granite Grub | Stamina endurance for long shifts |
| 21-30 | Gems, crystal clusters | Crystal Wisp | Bonus yield on gem nodes |
| 31-40 | Dark ore, rare minerals | Deep Dweller | Immune to dark penalties |
The transition between Depth 20 and 21 represents the biggest difficulty spike in the game, because gem nodes require the Crystal Wisp bonus to extract efficiently. Players who neglect to acquire this type before reaching that threshold report significantly slower progression, since standard miners waste time on nodes they cannot fully exploit.
Situation-Specific Selections
Beyond depth considerations, certain situations call for specialized choices. During incursion events, the Ember Sprite becomes invaluable because its ignition ability clears impurities faster than any other type, even though its low stamina requires careful management. For long overnight mining sessions, Granite Grub and Deep Dweller outperform faster types because they stay awake longer without intervention.
The Friendship Wool buff pairs exceptionally well with Pebble Puff during burst mining windows, since the speed boost compounds with the crit chance to produce dramatic short-term yields. Saving this item for moments when you need rapid resource generation, like before a major Village upgrade, maximizes its value.
Advanced Mini'Oh Strategies for Incursions and Events
Incursion events represent the highest-risk, highest-reward content in Hole Is Mine, and your Mini'Oh composition determines success or failure. The prologue changelog confirmed that Twitch integration allows chat to wake or stun minions during these events, which adds a social layer that can either help or hinder your runs.
Preparing Your Crew for Incursions
Successful incursion runs start with preparation before you even enter the event. Ensure every Mini'Oh is fully rested and happy, because the event duration does not pause stamina drain. Stock at least two Friendship Wool items for emergency recovery, and consider cloning your best utility type beforehand to field a specialized team.
| Preparation Step | Time Investment | Impact on Success |
|---|---|---|
| Full stamina restore | 10 minutes | Critical |
| Happiness boost to 100% | 5 minutes | High |
| Clone key utility type | 15 minutes | High |
| Equip best mining gear | 5 minutes | Medium |
The equipment system plays a significant role here, and our best equipment guide covers the optimal loadouts for maximizing Mini'Oh output during intense mining windows. Combining the right gear with a well-rested crew creates a multiplier effect that dramatically increases event rewards.
Managing the Social Interaction
The Twitch integration feature means that viewers can wake or stun your minions during incursions, which creates an unpredictable element that requires adaptive management. Community reports indicate that coordinated chat participation can significantly boost output when viewers consistently wake sleeping minions, but trolls can disrupt runs by stunning your best miners.
Experienced players recommend keeping a reserve of Friendship Wool specifically for counteracting stuns during streamed incursions, since the instant recovery lets you bounce back from disruptions quickly. The mini'oh launch guide covers advanced deployment patterns that help you maintain production even when individual minions get stunned.
Frequently Asked Questions
What is the best mini'ohs setup for beginners?
Start with two Pebble Puffs for fast early mining and one Granite Grub for endurance during longer expeditions. This combination covers both quick resource generation and sustained output while you learn the care mechanics. Upgrade your rest zones before expanding your crew, because more Mini'Ohs without proper rest facilities creates a bottleneck.
How do I keep my Mini'Ohs awake longer?
Build rest zones before expanding mining capacity—they accelerate stamina recovery significantly. Keep happiness above 70% with treats and rotate exhausted Mini'Ohs out while fresh ones work. Save Friendship Wool for incursion emergencies. The care and customization guide details feeding strategies that extend awake time by up to 40%.
Can I clone any Mini'Oh type?
Cloning requires the special item found during incursion events, and it works on any Mini'Oh that is awake and healthy. However, community testing suggests prioritizing rare utility types like Deep Dweller or Ember Sprite, since common miners appear frequently through normal exploration. The clone retains the original's level and equipment.
What happens when a Mini'Oh sleeps mid-mine?
A sleeping Mini'Oh stops mining entirely and produces nothing until you wake it, which wastes valuable extraction time. The complete mini'ohs list includes wake-up times for each type, helping you plan rotations around the longest sleepers. Setting a regular check-in routine prevents most mid-mine collapses.
Do different Mini'Ohs prefer different foods?
Yes, each Mini'Oh type prefers specific foods that trigger a 15% efficiency bonus when matched correctly. Consult the best minions guide for documented preference charts, or experiment with treats to discover favorites. Feeding wrong foods still restores happiness, just without the bonus, so prioritize matching for maximum mining output.
