Finger Carving Seal

The user concentrates chakra into their finger and using the heat from that, can apply writing of whatever they want to a surface. This technique however requires them to be very delicate with their chakra control. This technique causes slight discomfort for a living target and if it is on flesh, it will scar, presumably remaining on the subject's flesh for the rest of their life.
