The Sage Art: Boil Release Rasengan is a visually striking energy sphere with a dynamic, swirling core of boiling chakra, emitting steam and heat waves. The core is a vibrant mix of orange and red hues, resembling molten lava, surrounded by a translucent, blue chakra shell that crackles with energy. The surface is highly detailed with swirling patterns that simulate the motion of boiling liquid, and the entire sphere glows intensely, casting a warm light in its vicinity. The Rasengan is medium-sized, roughly the diameter of a basketball, with a slightly irregular shape due to the turbulent energy within.
