Request>how to activate 2x dmg on specific area cell/70 degree angle

[Emad]

i want  2xhit dmg activated if i moved from the mob only on the corner line/curved line  without straight lines/cells based on player prespective

example: A=PLAYER, m=mob,  x= 2xdmg activation line
Note: the skill is ground skill so in order to able to activate the self-collision the skill must hit on the curved line of the monster = mostly 70 ْ degree angel

                                           x            x
                                              x      x
                                                 m   
                                            x    A   x
                                          x              x
                                                 m
                                           x           x       
 

Thanks
