This powder is used to curse an enemy.  It is not a joke, cursing someone is serious business. you should NEVER do a curse when you are angry, you will send out more vibes that you intended that way and it wont be an easy thing to pull into check.

Cursing someone should be very well thought out and planned so that you don't cause it to jump up and bite you in the ass. And if you do it wrong, it WILL jump up and bite you in the ass.
