How it works
- Instructor heroes determine the shared Drill Camp training level.
- Heroes placed in training slots inherit that level without consuming Hero XP.
- Removing a hero restores its independently earned level.
Instructors, skills and slot cooldown
The five highest-level heroes act as Drill Instructors. Heroes in slots inherit the lowest instructor level; they can still gain stars and skill upgrades but cannot be levelled manually while in a slot. Removing a hero restores its prior level and leaves the slot unavailable for 24 hours.
