Help with making a spell

[mightchaos]

Already tried once and got trolled... So ya can anyone help me Take some amount of gold away from my grandfather which as I tried to explain, WILL NOT help my family out at the time of the world collapse I know his true colors, and he is the most unpleasant person I've ever met, yet people call me a troll, So this is going to be my first spell and I'm not sure how to do it, NO i'm not asking anyone to do it. I want some experience of my own, I'm just not sure if it should be through some kind of thought form with runes and affirmation or something else. Oh and 90% of the gold I take will be for the advancement of Satanism.

NOTE: IF YOU THINK I'M LYING OR JUST SOME TROLL THEN FUCK OFF! I would like some actual help please.

Hail Satan
Hail Astaroth
