Wave-Makers are a subset of Bloodless who fight using waves of dark energy.
Wave-Makers fire two wave-shaped projectiles in quick succession, turning to target Zagreus with each attack. As of the Murder Death Kill update, these waves pass through obstacles.
'...One-time scions of so many long-forgotten cults, which worshipped monsters slain by heroes at some point, these remnants of the living yet possess capacity to give a certain shape to diabolic energies. Within these waves of devastation lie their memories of their hate-filled transgressions, which they re-live and re-create again and again, much like the ocean's wave lapping somewhere against brittle and uncaring shores.'
