The materials you need is:
1) A sword, *I don't care what kind of sword ; saber, wooden sword etc*
2) Some green clothes
3) A blond wig
4) And a shield Okay, start off with a slight swing of your sword towards the right
*Yes, that's how you do it*
Then, do an upper sword cut, just to be sure that your sword slashes would look uber epic.
*Oh yeah, that's more like it*
Now, this is the most critical period of all. At this point on, the slashing technique that you're about to use will be the killing blow whenever you are fighting your enemy. So, you have to make sure this one hit it big time. Now, hold the sword above your head.. and bring your whole wrath upon you target! JUST LIKE THIS!
*Congratulation, you have successfully killed someone*
p/s: This technique will only work once you kidnap your enemy, and then sedate them with drugs so that they would be defenseless. Happy hunting~
