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 called sometimes called 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. These weaves were shown Rand when Lews Therin gained control of the One Power in Knife of Dreams.
