Fire Blossom

From A Wheel of Time Wiki

Using Earth, Air, and Fire the channeler creates a bar of fire less than the width of an average forearm, and about ten feet tall. These "bars of red" as they are called sometimes make a high pitched whining sound. When another flow of Air is added in, these bars explode to thirty feet across, incinerating and throwing enemies across the battlefield.

Along with Arrows of Fire and Deathgates, Fire Blossoms are a recently rediscovered combat weave used by the Asha'man. Lews Therin showed these weaves to Rand when he gained control of the One Power in Knife of Dreams.
