Stregone che evoca un incantesimo di nebbia viola scura vorticosa

An epic depiction of a powerful warlock summoning a dark, misty purple spell, shrouded in an ethereal, haunting glow. The warlock stands with his hands raised, channeling a swirling vortex of thick, smoky purple mist that radiates ominous energy. The mist snakes outward like ghostly tendrils, forming spectral shapes of skulls and wraithlike figures that dissolve into the surrounding shadows. His dark, tattered robes billow unnaturally as if moved by the energy of the spell, adorned with faintly glowing runes.
