The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra that combines the traditional Rasengan's spiraling energy with the unique properties of Boil Release. The core is a bright, luminous blue, representing the dense chakra, surrounded by swirling steam and heat waves in shades of orange and red, indicating the boiling effect. The surface is highly dynamic, with the energy constantly moving and shifting, creating a sense of intense heat and power. The overall shape is spherical but slightly irregular due to the volatile nature of the steam, with the edges appearing more fluid and less defined than a standard Rasengan.
