Description: The user snaps their finger towards a direction that they want to explode in a small wave of fire. The destruction varies on every rank. The area of affect varies on rank as well. At D rank the damage is strong enough to leave burning marks behind, it would be first degree, at this point it is painful. At C rank the damage increases to long lasting burn marks which injure the skin second degree, this one is very painful. At B rank the fire injures the skin potentially permanently at third degree which is painless and so is the rank above. At A rank the third degree burns are permanently unless removed by a extremely skilled medic nin. At S rank and higher the burns are fourth degree, which destroys nearly everything.

The jutsu works with a flint being thrown towards a direction, this flint is very thin and resembles lightning. Upon arriving at the point of where Nick wants it to detonate it the tip of the 'flint' would explode. The 'flint' is somewhat hard to notice but it is noticeable to the naked eye. The flint is very hard to move out of it's original way unless strong winds are used. Here's the minimal and maximum speed of the flint:

D Rank - 25mp/s
C Rank - 45mp/s
B Rank - 65mp/s
A Rank - 85mp/s
S Rank - 105mp/s

Here's a chart from wikipedia to show how badly the skin would be damaged, warning, this image is graphic, if you're eating or you're already feeling dizzy- you have a weak stomach? Skip this one, do yourself a favor:
