The Sage Art: Lava Release Rasengan is a powerful, swirling sphere of chakra infused with molten lava, creating a visually striking and dangerous attack. The core of the Rasengan is a bright, glowing orb of blue chakra, surrounded by a turbulent, orange-red lava that crackles and emits heat distortion effects. The lava forms irregular, flowing patterns around the chakra core, giving it an organic, dynamic appearance. The entire sphere is enveloped in a faint, fiery aura, with occasional sparks and embers flying off. The Rasengan is medium-sized, roughly the diameter of a basketball, but its intense energy makes it appear larger and more imposing. The surface is highly textured, with the lava appearing rough and molten, while the chakra core is smooth and luminous. The colors are vibrant, with the blue chakra contrasting sharply against the fiery lava, and the overall effect is both mesmerizing and intimidating.
