Fire Emblem Heroes uses a grid-based, turn-based combat system. Each hero has a movement range and can attack adjacent or ranged foes. The 'Weapon Triangle' is fundamental: Red (Sword, Red Tome, Red Breath) beats Green (Axe, Green Tome, Green Breath), Green beats Blue (Lance, Blue Tome, Blue Breath), and Blue beats Red. Colorless units (Bow, Dagger, Staff, Colorless Breath) have no inherent advantage or disadvantage against the primary colors. Understanding this triangle is crucial for positioning your units and predicting combat outcomes. Always try to engage enemies with a weapon triangle advantage for increased damage and reduced incoming damage.
