Attack, Defense, and Health all function together rather than as a simple Attack vs Defense system, and they generally apply equally whether a unit is attacking or defending. Attack determines the damage a unit deals, Defense reduces incoming damage, and Health defines how much damage it can take before being defeated. The key difference in this game is the unit-type advantage system (like 25% or 50% bonuses), which can significantly influence combat outcomes meaning a unit with lower stats can still perform better if it has a strong advantage over the enemy type. So overall, stats are consistent in both roles, but matchups and percentage modifiers play a major role in determining the final result.
