In his dimly lit training room, the air crackled with the intense energy of Lucifer's magical practice. His eyes focused and his body taut with concentration, Lucifer deftly combined his fire and earth affinities. With a swift motion, he conjured sharp, molten lava knives that glowed with a fierce, fiery intensity. Manipulating them with his aura, he launched them towards various targets set up across the room. Each knife struck with precision, embedding itself deeply into the marks, sending sparks and shards of rock scattering.
Sweat glistened on Lucifer's brow as he continued his relentless practice. He moved with fluid grace, each motion deliberate and controlled. The lava knives danced in the air, guided by his will, forming intricate patterns before finding their targets. The room echoed with the sounds of impact and the sizzling of molten rock cooling upon contact.
