They Are Billions Calliope — Build

Calliope is the high-agility, rapid-fire hero in the They Are Billions campaign. Unlike her counterpart Caelus, she relies on kiting, high attack speed, and movement to survive tactical missions. A successful Calliope build focuses on overcoming her natural weaknesses—low damage and short range—to ensure she can handle elite threats like Harpies and Spitters.
