Whiteout Survival Drill Camp Guide: Instructors, Slots, and Level Reset

The Drill Camp is one of the best ways to save Hero XP in Whiteout Survival. It unlocks at Furnace Lv. 13 and automatically uses your five highest-level heroes as Drill Instructors. Heroes placed in Drill Slots then match the level of your lowest-level instructor without requiring you to spend Hero XP on each one individually.

The key is to concentrate manual leveling on five heroes and keep those instructor levels relatively balanced. The Drill Camp can eventually provide up to 15 Drill Slots as your Furnace progresses from Lv. 13 to Lv. 30, giving you a much larger usable roster without manually leveling every hero.

What Is the Drill Camp in Whiteout Survival?

The Drill Camp is a hero progression feature found through the Heroes menu after reaching Furnace Lv. 13. It has two main functions:

1. Level Drills: temporarily synchronize heroes in Drill Slots with the lowest-level Drill Instructor.
2. Level Resets: reset a manually leveled hero and recover the Hero XP invested in that hero.

Together, these systems let you concentrate Hero XP on a small core of heroes while keeping much more of your roster at a useful level.

Drill Camp Feature	How It Works
Unlock requirement	Furnace Lv. 13
Drill Instructors	Five highest-level heroes
Drill level	Level of the lowest Drill Instructor
Maximum Drill Slots	15
Slot progression	Additional slots unlock as the Furnace progresses from Lv. 13 to Lv. 30
Hero XP for slotted heroes	No manual XP is required to receive the Drill level
Maximum hero level	Lv. 80
Level Reset	Allows previously invested Hero XP to be recovered and reallocated

The Drill Camp only solves the hero level part of progression. Hero stars, skills, Hero Gear, Exclusive Gear, and other independent upgrades still need to be managed separately.

How the Whiteout Survival Drill Camp Works

Drill Instructors

Your five highest-level heroes automatically become Drill Instructors. Instructor selection is based on hero level rather than Hero Gear or total displayed power.

The important number is the level of the fifth instructor—the lowest level among the five—because that becomes the level granted to every hero assigned to a Drill Slot.

Drill Instructor	Example Level
Instructor 1	65
Instructor 2	65
Instructor 3	64
Instructor 4	64
Instructor 5	60
Resulting Drill Level	60

In this example, leveling Instructor 1 from 65 to 66 does nothing for the heroes in Drill Slots. Raising Instructor 5 is what increases the camp’s effective level.

Drill Slots

Drill Slots hold the other heroes you want to benefit from the camp. A low-level hero placed into a slot is synchronized to the Drill level while assigned there.

This lets a newly unlocked or previously neglected hero become usable without consuming the Hero XP needed to manually bring that hero up to the same level.

Up to 15 Drill Slots become available through Furnace progression. The official Drill Camp information notes that slots appear frequently at earlier Furnace levels and become more spread out later, so do not assume every Furnace upgrade will always add another slot.

Actual Level vs. Drill Level

It is useful to distinguish between two types of levels:

• Actual level: the hero level obtained by spending Hero XP directly.
• Drill level: the synchronized level the hero receives while occupying a Drill Slot.

The Drill Camp does not convert the temporary level into permanent Hero XP progression. If you remove the hero from the slot, the Drill Camp boost no longer applies.

How Drill Instructors Are Chosen

You do not manually pick five instructors from a separate selection screen. The system automatically identifies your five highest-level heroes.

That changes how you should think about instructor strategy. You are not really choosing instructors directly—you are choosing which five heroes receive enough Hero XP to remain your highest-level heroes.

Hero Attribute	Determines Instructor Selection?
Hero level	Yes
Hero rarity	No; level determines selection
Star level	No; level determines selection
Skill levels	No; level determines selection
Hero Gear	No
Exclusive Gear	No; level determines selection
Total displayed power	No; level determines selection

This is why an older Epic or Rare hero can remain an instructor even after you unlock a stronger Mythic hero: if the older hero has the higher actual level, the Drill Camp still recognizes that level.

Best Drill Instructor Strategy

The most efficient setup is usually to spend Hero XP directly on five heroes you use frequently and expect to keep useful, then let Drill Slots handle most of the rest of your roster.

There is no requirement to maintain one instructor of each troop type. Your five instructors are determined by level, so prioritize useful heroes rather than forcing a specific Infantry/Lancer/Marksman ratio just for Drill Camp.

Keep the Five Instructor Levels Close

Keeping the five levels close together usually gives the best return on Hero XP because every increase to the lowest instructor immediately raises the synchronized level of your Drill Slot heroes.

Level Pattern	Drill Level	Efficiency
60, 60, 60, 60, 60	60	Excellent balance
62, 61, 61, 60, 60	60	Reasonable
70, 68, 65, 60, 52	52	Poor for Drill Camp progression

This does not mean all five must remain identical at every moment. Your main Arena or Exploration hero may deserve an extra level first when that immediate power increase helps you clear content. The mistake is allowing the fifth hero to remain far behind for long periods.

Do Your Instructors Need to Be Your Five Best Heroes?

Not necessarily in terms of rarity or raw combat potential. They should ideally be heroes you are comfortable leveling directly because Hero XP invested in instructors cannot simultaneously be used elsewhere.

For most players, frequently used combat heroes make sensible instructors. As newer hero generations replace older heroes, the Level Reset system gives you a way to reorganize that XP instead of remaining permanently committed to your original five.

Best Heroes for Drill Slots

A Drill Slot is most valuable when it saves Hero XP on a hero you actually use. Filling all available slots with random low-priority heroes provides less practical benefit than prioritizing your active roster.

Priority	Good Drill Slot Candidates	Why
1	Useful newly unlocked heroes	Become usable immediately without a large Hero XP investment
2	Arena and Exploration heroes outside your five instructors	Hero level directly matters in these modes
3	Secondary combat heroes	Useful when you need more than one effective formation
4	Rally and event support heroes	Keeps supporting heroes at a useful level without direct XP
5	Lower-priority gathering or development heroes	Fine for spare slots after combat priorities are covered

New-Generation Heroes

New heroes often arrive at a low level even when their generation makes them attractive replacements for older heroes. Placing them in a Drill Slot lets you use or test them immediately without resetting an established instructor first.

If the hero becomes a long-term core member, you can later decide whether to give that hero direct XP and move it into your instructor group.

Arena and Exploration Heroes

Arena and Exploration use multiple heroes, making Drill Camp especially valuable for maintaining a broader combat roster. Prioritize characters that actually appear in your formations instead of filling early slots with heroes you rarely field.

Rally Joiners and Event Heroes

Some heroes are useful because of their Expedition skills or specific event roles rather than because they need to become one of your five permanently leveled heroes. Drill Slots can keep those heroes appropriately leveled while your direct XP remains concentrated elsewhere.

This is useful for recurring activities such as Bear Hunt and other alliance content where different heroes may have specialized uses.

Gathering Heroes

Gathering heroes can use spare Drill Slots, but combat heroes usually deserve the first available spaces. Many gathering benefits come from hero skills rather than simply raising the hero’s level, so putting a gathering hero in Drill Camp is often lower priority.

How Level Reset Works

The second major Drill Camp feature is Level Reset. It lets you reset a hero’s manually invested level and recover the Hero XP previously spent on that hero.

This is particularly useful after Furnace Lv. 13 because early-game players commonly spread XP among many heroes before Drill Camp becomes available.

How to Reset a Hero

1. Open the Heroes menu.
2. Enter Drill Camp.
3. Open the Level Resets section.
4. Select the hero you want to reset.
5. Review the reset confirmation.
6. Confirm the reset.
7. Reallocate the recovered Hero XP where it provides more value.

A good early Drill Camp cleanup is often to reset lower-priority heroes that received manual XP, concentrate that recovered XP into your five intended instructors, and then place the reset heroes into available Drill Slots.

When Should You Reset a Hero?

Level Reset is useful when a hero:

• Was leveled heavily during the early game but is no longer a priority.
• Can get the level it needs from an available Drill Slot instead.
• Has been replaced by a newer-generation hero.
• Is occupying one of the five instructor positions when you want another hero there.
• Received Hero XP accidentally.

How to Change a Drill Instructor

Because instructor selection is automatic, replacing an instructor usually means changing the actual hero levels that determine your top five.

A common method is:

1. Reset the instructor you want to remove.
2. Its manually invested level drops through the reset process.
3. The next eligible high-level hero can move into the five-instructor group.
4. Use the recovered Hero XP on the heroes you want to keep directly leveled.

Check all of your hero levels before making the change. The system follows level, so your replacement instructor may not be the hero you expected if another character already has a higher actual level.

Drill Slot and Level Reset Cooldowns

The Drill Camp has two different 24-hour cooldown rules, and confusing them can make roster changes unnecessarily frustrating.

Action	Cooldown Rule	Can Gems Reduce It?
Remove a hero from a Drill Slot	The empty slot cannot be reassigned for 24 hours	No
Reset a hero, level that hero again, then attempt another reset	The hero has a 24-hour Level Reset restriction	Yes
Hero is deployed	Hero must return before eligible Drill Camp changes	Not applicable

Deployed Heroes Cannot Be Removed or Reset

Heroes currently away on deployment cannot be removed from Drill Slots or have their level reset. This includes heroes being used for activities such as gathering, beast or Polar Terror hunting, and battles.

If a hero is unavailable when you want to reorganize the camp, let the deployment finish or return the hero first.

Best Drill Camp Strategy for F2P Players

Drill Camp is particularly valuable to F2P players because Hero XP becomes far more efficient when most of the roster receives levels through synchronization.

1. Stop Manually Leveling the Whole Roster

Once Drill Camp is unlocked, there is usually little reason to keep spending XP evenly across every hero. Focus direct XP on the five heroes forming your instructor group.

2. Recover Early-Game Hero XP

Review heroes you leveled before Furnace Lv. 13. If they can function through Drill Slots instead, Level Reset can free that XP for your instructor group.

3. Raise the Lowest Instructor

Whenever you want to improve the Drill Camp, identify the lowest instructor. Raising a hero already several levels ahead of that instructor will not change the synchronized level.

4. Fill Slots by Actual Usage

Prioritize heroes you use in Arena, Exploration, PvP, alliance content, rallies, and secondary formations. A slot has more value when it saves XP on a hero that regularly contributes to your account.

5. Plan Around New Hero Generations

Do not reorganize every slot immediately before expecting a useful new hero. Because removing a slotted hero triggers an unavoidable 24-hour slot cooldown, planning ahead makes new unlocks easier to integrate.

6. Revisit the Instructor Group Over Time

Your ideal five manually leveled heroes can change as your state unlocks newer generations. Level Reset means your early instructor setup does not have to remain permanent.

What Drill Camp Does Not Replace

A synchronized level can make a hero much more usable, but hero level is only one part of Whiteout Survival progression.

Hero Progression	Handled by Drill Camp?
Hero level	Yes, temporarily for slotted heroes
Star ascension	No
Hero skills	No
Hero Gear	No
Exclusive Gear	No

A newly unlocked hero can therefore reach your Drill level immediately and still need shards, skill materials, gear, or Exclusive Gear development before matching a fully built older hero.

If your goal is to begin with more hero and Furnace progression already completed rather than developing a fresh roster through Drill Camp, a wos account for sale is an optional alternative. Check the specific account’s hero generation, Furnace or Fire Crystal level, hero development, gear, and other progression before deciding.

Common Drill Camp Mistakes

Spreading Hero XP Across Too Many Heroes

The main purpose of Drill Camp is to avoid this problem. Concentrating XP on five instructors lets many more heroes receive useful levels through Drill Slots.

Ignoring the Fifth Instructor

This is the most important leveling mistake. The lowest instructor determines the Drill level, so an underleveled fifth hero holds back every slotted hero.

Trying to Pick Instructors Manually

Instructor positions are determined automatically by hero level. To change the group, change which heroes occupy your five highest actual levels, using Level Reset when appropriate.

Removing a Slotted Hero Right Before You Need the Slot

A removed hero causes a 24-hour cooldown before that slot can accept another hero, and Gems cannot bypass it. Plan roster changes ahead of important unlocks.

Trying to Change a Deployed Hero

Heroes away on deployment cannot be removed from their Drill Slot or level-reset. Return them first.

Assuming Drill Level Means the Hero Is Fully Built

Level synchronization does not replace stars, skills, gear, or other progression systems. A Lv. 80 Drill hero can still be much weaker than another Lv. 80 hero with stronger development elsewhere.

FAQ

When does Drill Camp unlock in Whiteout Survival?

Drill Camp unlocks at Furnace Lv. 13 and can be accessed through the Heroes menu.

How are Drill Instructors chosen?

Your five highest-level heroes automatically become Drill Instructors. Their Hero Gear or total displayed power does not determine the instructor positions.

What determines the Drill Camp level?

The lowest level among your five Drill Instructors determines the Drill level. Every hero assigned to a Drill Slot synchronizes to that level.

How many Drill Slots are there?

Whiteout Survival currently provides up to 15 Drill Slots. Additional slots become available as your Furnace progresses from Lv. 13 through Lv. 30.

What happens when you remove a hero from a Drill Slot?

The hero loses the synchronized Drill level, and the vacated slot enters a 24-hour cooldown before another hero can be assigned. That slot cooldown cannot be reduced with Gems.

Does Level Reset return Hero XP?

Yes. Level Reset lets you recover the Hero XP invested in the selected hero so it can be reallocated. If you level that same hero again after resetting it, a 24-hour restriction applies before another reset; unlike the Drill Slot cooldown, this reset cooldown can be reduced with Gems.

Conclusion

The Whiteout Survival Drill Camp is most efficient when you concentrate Hero XP on five useful instructors, keep the lowest instructor from falling too far behind, and use Drill Slots for the rest of your active roster. Level Reset lets you reorganize that investment as stronger heroes become available, while careful slot planning prevents the 24-hour cooldown from blocking new additions.
