Safe progression teams
For campaign pushing, prefer stable control and leak protection over peak damage. A slower but safer team helps identify tower mistakes because it keeps enemies inside the map long enough to learn from each wave.
Lineup Notes
Lineup Planning
Different maps ask different questions: flying enemies, bulky waves, split lanes, and Boss burst each need different hero combinations.
Team Building Principles
Build a lineup around the map's question
A good Realm Defense lineup has a job for every slot. One hero should define control or damage, the second should cover the biggest weakness, and the third should protect against the wave type that usually causes leaks.
Boss-focused teams
Boss stages need saved burst, not constant small skill use. Pair a Boss answer with crowd control so normal waves do not slip through while the team is busy holding the main target in range.
Flexible swaps
If a recommended hero is missing, swap by function. Replace anti-air with another anti-air tool, summons with another delay source, and tower support with a hero who extends the same kill-zone uptime.
