The Training Base in Last War: Survival produces Hero EXP automatically, making it one of the most important buildings for developing a stronger squad. Upgrading it consistently gives you more Hero EXP per hour and helps your main heroes reach higher levels faster.
However, Training Base upgrades become increasingly expensive. You need to balance Iron, Food, Coins, construction time, and your other base priorities to avoid slowing down overall progression.
How the Training Base Works in Last War
The Training Base generates Hero EXP every hour. The higher its level, the more EXP it produces, allowing you to improve your heroes without relying entirely on missions, events, or consumable EXP items.
You can begin building Training Bases early in the game, and your account can eventually support up to five of them. Developing several Training Bases creates a reliable long-term source of Hero EXP, which becomes increasingly valuable as hero level requirements grow.
Training Base production is especially useful when developing multiple heroes for different squads. However, you should still prioritize heroes that fit your main formation rather than dividing EXP equally among every character.
For a broader explanation of EXP sources and leveling priorities, read the Last War Hero EXP guide. It explains how Training Base production fits alongside other methods of leveling your heroes.
How to Optimize Your Training Bases
Simply constructing a Training Base is not enough. You need to upgrade it consistently and coordinate its development with the rest of your base.
- Upgrade consistently: Each Training Base level increases hourly Hero EXP production, so avoid leaving the building far behind your overall base level.
- Build multiple Training Bases: You can have up to five, allowing you to create a much larger combined EXP income.
- Manage resources carefully: Upgrades require Iron, Food, and Coins, especially at higher levels.
- Use research bonuses: Economic and construction research may reduce upgrade times or improve your overall development efficiency.
- Prioritize important heroes: Spend the generated EXP on heroes used in your main squads before investing heavily in secondary characters.
- Check production regularly: Monitor whether your EXP income is keeping pace with the increasing cost of hero levels.
- Use alliance assistance: Request alliance help to reduce construction time whenever you upgrade a Training Base.
Training Base Upgrade Requirements
Training Base upgrades require progressively larger amounts of Iron, Food, and Coins. Construction times also increase significantly at higher levels, so planning ahead becomes essential.
The table below shows selected Training Base levels, their approximate upgrade requirements, power gains, and hourly Hero EXP output.
| Level | Iron | Food | Coin | Upgrade Time (Approx.) | Power | EXP Output/hr |
|---|---|---|---|---|---|---|
| 1 | 10 | 10 | – | 1s | 600 | 1,440 |
| 5 | 3,400 | 3,400 | – | 2m 56s | 3,000 | 7,920 |
| 10 | 62,000 | 62,000 | 20,000 | 42m 36s | 6,000 | 20,880 |
| 15 | 570,000 | 570,000 | 180,000 | 2h 50m 18s | 10,800 | 48,960 |
| 20 | 5,000,000 | 5,000,000 | 1,600,000 | 15h 15m 52s | 23,100 | 108,000 |
| 25 | 24,000,000 | 24,000,000 | 7,700,000 | 2d 17h 43m 49s | 51,300 | 162,000 |
| 30 | 120,000,000 | 120,000,000 | 39,000,000 | 13d 6h | 116,000 | 259,200 |
These values should be treated as base estimates. Research, construction bonuses, survivor effects, alliance assistance, and game updates may change the final resource costs or completion times shown on your account.
When Should You Upgrade the Training Base?
You should generally keep your Training Bases reasonably close to your Headquarters level. However, they should not automatically take priority over buildings required for Headquarters advancement, troop development, research, or healing capacity.
Prioritize a Training Base upgrade when:
- Your main heroes are leveling too slowly.
- Your Training Bases are several levels behind your Headquarters.
- You have enough resources without delaying a more important building.
- A construction or power event rewards building upgrades.
- You are preparing to develop a new primary squad.
You may delay the upgrade temporarily when another structure is required for your next Headquarters level. The Last War Headquarters upgrade guide can help you identify upcoming building requirements before committing a construction queue.
Why Maxing Your Training Bases Matters
A level 30 Training Base produces 259,200 Hero EXP per hour before any additional bonuses. When several high-level Training Bases are operating together, they provide a substantial and consistent source of EXP.
This allows you to strengthen your heroes more efficiently, develop additional squads, and prepare characters for tougher campaign stages, PvP battles, alliance events, and seasonal content.
However, upgrading all five bases to the maximum level requires a considerable amount of resources and construction time. It is usually more efficient to develop them gradually alongside your Headquarters and other essential buildings.
Common Training Base Mistakes
- Spreading EXP across too many heroes: Focus first on characters used in your strongest squad.
- Ignoring resource requirements: High-level Training Base upgrades can consume resources needed for Headquarters or troop buildings.
- Upgrading without checking events: Starting a long upgrade immediately before a construction event can reduce the rewards you receive.
- Neglecting multiple bases: One high-level Training Base may produce less combined EXP than several consistently developed bases.
- Leaving EXP unused: Regularly apply available Hero EXP to characters that provide immediate value to your formations.

Research and other bonuses may reduce construction time, lower effective costs, or improve your general progression efficiency.
Is it worth maxing all Training Bases?
Yes, but it is usually best to upgrade them gradually. Prioritize essential Headquarters and troop-building requirements before investing all your resources into maximum-level Training Bases.
How much EXP does a level 30 Training Base produce?
A level 30 Training Base produces 259,200 Hero EXP per hour before additional bonuses.

Conclusion
The Training Base is a valuable long-term source of Hero EXP in Last War: Survival. Building several bases and upgrading them consistently can significantly accelerate hero development, especially as higher hero levels require larger amounts of EXP.
Balance Training Base upgrades with your Headquarters, research buildings, troop facilities, and resource economy. A planned approach will help you strengthen your main squad without delaying other essential parts of your base.
