Description: You can focus the purity of Osano-Wo's fire into a searing physical blow or blast nearby enemies with a sheet of fire.

Prerequisites: Improved Unarmed Strike, Void Use, 10th Level Inkyo

You may spend a Void Point when making an unarmed attack to release the Fire within you. In addition to the physical damage from the attack, a thin sheet of flame explodes from your open palm, swirling around your body. This flame does 5d4 fire damage in all squares adjacent to you (Reflex DC 10 + Dex Modifier + 1/2 your total monk and inkyo levels). The target of your original attack is not allowed a save.
