The Hospital is the primary building used to heal wounded troops in Last War Survival. Its capacity determines how many injured units can recover after battle before additional casualties risk being permanently lost. This guide covers how the Hospital works, its upgrade costs, capacity increases, and practical ways to protect more of your army.
Understanding the Hospital
The Hospital is where wounded troops are sent after eligible battles. Instead of losing those units permanently, you can heal them and return them to active duty.
However, Hospital capacity is limited. When the number of injured troops exceeds the available Unit Limit, some overflow casualties may be permanently lost. Upgrading the Hospital increases its capacity and allows more troops to survive heavy battles.
Once your Headquarters reaches level 22, you can unlock the Emergency Center. This building can rescue a percentage of eligible troops that overflow from the Hospital, providing an additional layer of protection against permanent losses.
The Hospital and Emergency Center should be developed together. The Hospital handles your primary wounded troop capacity, while the Emergency Center supports units that cannot fit inside it.
Hospital Upgrade Costs and Capacity
Each Hospital upgrade increases its Unit Limit and building power. Higher levels allow your base to hold more wounded troops, but the resource requirements and construction times also rise significantly.
The table below shows the supplied Hospital upgrade milestones:
| Level | Iron Cost | Food Cost | Coin Cost | Unit Limit | Power | Upgrade Time |
|---|---|---|---|---|---|---|
| 1 | 30 | 90 | – | 650 | 700 | 6s |
| 5 | 6,800 | 20,000 | – | 850 | 3,500 | 11m 42s |
| 10 | 190,000 | 560,000 | 150,000 | 1,100 | 7,600 | 4h 15m 32s |
| 15 | 1,700,000 | 5,100,000 | 1,400,000 | 1,350 | 19,200 | 10h 11m 50s |
| 20 | 15,000,000 | 45,000,000 | 12,000,000 | 1,600 | 49,800 | 3d 50m 46s |

| 30 | 360,000,000 | 1,100,000,000 | 290,000,000 | 2,000 | 283,400 | 41d 7h 15m 52s |
| 31 | 400,000,000 | 1,200,000,000 | 320,000,000 | 2,020 | 329,600 | N/A |
| 32 | 440,000,000 | 1,300,000,000 | 350,000,000 | 2,040 | 377,900 | N/A |
| 33 | 480,000,000 | 1,400,000,000 | 380,000,000 | 2,060 | 428,100 | N/A |
| 34 | 500,000,000 | 1,500,000,000 | 400,000,000 | 2,080 | 479,800 | N/A |

Important Note: The listed values are base requirements. Research, alliance technology, profession bonuses, the Builder’s Hut, VIP perks, and other active effects may reduce your actual costs or construction time.
When Should You Upgrade the Hospital?
The Hospital deserves higher priority when your wounded troop count frequently approaches its capacity. Players who participate in regular PvP, alliance wars, or other high-casualty activities usually benefit more from additional Hospital levels.
You should also upgrade it when it is required for your next Headquarters level. The Hospital appears as a prerequisite at several important HQ milestones, so neglecting it can eventually delay wider base progression.
If your Hospital rarely fills, another building may provide more immediate value. Review your normal casualty levels before committing large amounts of Iron, Food, Coin, or advanced resources.
Hospital and Emergency Center Priorities
The Hospital should usually remain your first troop recovery priority because it directly stores wounded units. The Emergency Center only becomes relevant after Hospital capacity has been exceeded.
A practical upgrade order is:
- Maintain enough Hospital capacity for your normal battle losses.
- Upgrade the Emergency Center after it unlocks at Headquarters level 22.
- Continue improving both buildings as your troop count and combat activity increase.
- Check both capacities before entering prolonged battles or server-wide conflicts.
Improving only the Emergency Center while leaving the Hospital underdeveloped is inefficient. A stronger Hospital reduces the number of troops that depend on overflow rescue in the first place.
Tips for Hospital Optimization
- Upgrade during relevant events: Construction events may reward building upgrades or power increases. Check the Last War Event Hub before starting a major Hospital upgrade.
- Monitor capacity before battle: Avoid entering another high-casualty fight while the Hospital is nearly full.
- Heal troops regularly: Begin healing wounded units as soon as practical so capacity becomes available for future battles.
- Balance resource production: Keep your Iron Mine, Farmland, and Gold Mine developed enough to support construction and healing costs.
- Use alliance assistance: Request help from alliance members during long upgrades. The Alliance Support Hub can improve the effectiveness of this assistance.
- Use speedups carefully: Save construction and healing speedups for major upgrades, important events, or urgent troop recovery.
- Review VIP benefits: Higher VIP levels may provide construction, healing, or progression bonuses. See the Last War VIP levels and perks guide for more details.
- Reduce unnecessary casualties: Better hero formations, troop statistics, research, and scouting can reduce the number of units sent to the Hospital.
How Hospital Capacity Supports Account Progression
Hospital capacity does not directly increase troop Attack or Defense, but it protects the resources and training time already invested in your army. Recovering wounded units is generally more efficient than replacing troops that have been permanently lost.
This becomes increasingly important as troop tiers and training costs rise. A major loss at higher account levels can require substantial resources and time to rebuild, making recovery infrastructure an important part of long-term progression.
For a broader explanation of the attributes that affect army performance, review the Last War troop stats guide.
Hospital Development and Account Value
A developed Hospital is particularly valuable on accounts with large armies and frequent combat activity. However, reaching a high Headquarters level while also upgrading recovery buildings, research, troops, and heroes can take months of consistent progression.
Players who prefer to begin with established military and recovery infrastructure can explore a Last War Survival account for sale through Heaven Guardian. Available accounts may include upgraded Hospitals, developed Emergency Centers, trained troops, stronger heroes, and progressed research, with lifetime warranty coverage and premium support for a safer purchase experience.
FAQs
Q: What happens when my Hospital is full?
A: Eligible injured troops that exceed the Hospital limit may overflow to the Emergency Center after it is unlocked. Troops exceeding all available recovery capacity may be permanently lost.
Q: How do I increase Hospital capacity?
A: Upgrade the Hospital to increase its Unit Limit.
Q: Is the Emergency Center worth upgrading?
A: Yes, especially when your Hospital frequently reaches capacity. It can preserve a percentage of eligible overflow casualties.
Q: Should I upgrade the Hospital or Emergency Center first?
A: Prioritize the Hospital because it is the primary destination for wounded troops. Upgrade the Emergency Center as additional overflow protection.
Q: Do different troop types use separate Hospital capacity?
A: The Hospital capacity shown by the building applies to eligible wounded units stored there rather than providing a separate limit for each troop type.
Q: Can I heal troops while my base is under attack?
A: Healing functions may remain available, but you should check your current battle status and any active restrictions before relying on them during an attack.
Q: How important is the Hospital compared with other buildings?
A: It is especially important for active combat players. However, its priority should remain balanced with the Headquarters, troop buildings, research, resource production, and Emergency Center.
Q: How can I reduce healing time?
A: Use relevant research, VIP benefits, buffs, items, alliance assistance, and other healing-speed bonuses available on your account.
Q: Is upgrading the Hospital beyond level 30 worthwhile?
A: It may be worthwhile for late-game accounts with large armies and frequent casualties. Compare the additional capacity with the resource and Oil costs of other advanced upgrades.
Conclusion
The Hospital is the main troop recovery building in Last War Survival. Increasing its capacity allows more wounded units to survive difficult battles and reduces the time and resources required to rebuild your army.
Keep the Hospital balanced with the Emergency Center, troop development, research, resource production, and your normal combat activity. Monitoring capacity and healing troops regularly will provide more protection than waiting until both recovery buildings are already full.
