Important Notes:
- The upgrade cost shown in the table above is the base value, meaning the actual cost will be slightly lower once research and other bonuses are applied.
- A single Training Base can generate 259,200 Hero EXP per hour at its maximum level. You can build up to 5 Training Bases, which adds up to over a million Hero EXP per hour. This makes it much easier to level up your heroes, so it’s a smart strategy to keep your Training Bases well-upgraded.
