Drill Core - How to Heal

Written by Jason B. | Drill Core

In Drill Core, healing revolves around a combination of passive systems, permanent unlocks, and smart tactics. Neither the core nor your workers regenerate health automatically or infinitely. Healing must be unlocked, resources managed carefully, and unnecessary risks avoided.

Core Healing

Core health restoration is only possible through specific upgrades. There are two key methods:

Core Repair Upgrade

Access the Upgrades menu from the main screen. One available option allows you to repair the drill platform by 300 HP. This is a one-time unlock that becomes accessible during missions once purchased.

Daily Full Core Restoration

Another upgrade fully restores the core’s HP at the beginning of each new day. This is far more efficient than incremental healing and is widely regarded as one of the most valuable survivability upgrades in endgame progression.

Using both upgrades in tandem significantly increases durability, especially when tackling deep zones or powerful enemies like Arachnor.

Worker Healing

Worker health recovery is also gated behind the Upgrades menu.

Once unlocked, miners, carriers, and guards gradually regain HP over time during daylight cycles. The regeneration rate is slow, so consecutive battles should be avoided. If a guard is heavily damaged, it's wise to pull back and avoid combat until their health recovers naturally.

There are no healing items, medical stations, or instant recovery options for workers in the field.

Damage Prevention Strategies

• Deploy 3 standard guards instead of investing heavily in one. It’s more cost-effective and provides better resilience.
• When a guard is injured, avoid combat for the remainder of the day.
• On the Ice Planet, frozen enemies only activate if a worker comes within approximately two tiles. You can often bypass or mine around them safely.
• Destroy spawner blocks before the enemy inside emerges. Right-click to mark them as priority and assign 2–3 miners to break them quickly.
• Steer clear of environmental hazards like black holes and geysers. These cause instant death, and no healing can counter that.

Healing Isn’t Enabled by Default

Every healing mechanism must be manually unlocked. The base game assumes you’ll take damage and lose units. Healing upgrades are designed to gradually reduce that attrition as you advance your tech and platform capabilities.

Final Thoughts

Healing in Drill Core is entirely upgrade-dependent. Core repair and daily full heal options extend your survival in prolonged runs. Worker healing is passive and gradual, so minimizing fights is essential. Strong defensive planning and situational awareness are more impactful than healing alone.

FAQ

How do I heal the core in Drill Core?

Purchase the core repair upgrade from the main menu. Alternatively, unlock the daily full heal upgrade, which resets your core to maximum HP at the start of each day.

Can I heal my workers?

Yes, but only after unlocking the worker healing upgrade. Once active, they will slowly regain HP over time during the day.

Is there a healing item or building?

No. There are no consumable healing items or active healing structures. All recovery is passive and dependent on upgrades.

What's the best way to avoid damage?

Use multiple guards rather than over-upgrading a single one. Focus on destroying spawner blocks before enemies emerge. Stay away from high-risk tiles such as black holes and geysers.

Should I heal my guards or replace them?

If your factories generate resources freely, replacing a guard may be faster than waiting for healing. However, healing becomes crucial during extended missions where replacement isn't practical.
