Need:
-Dirt
-Pentagram
Draw a pentagram in the dirt and sprinkle dirt on the pentagram and say:
"Within these points and lines and stars
The strength within to rule as Zars
Will appear as muscle and flesh
To be the strongest to be the best
Enchant this soil within your realm
And let the others be overwhelmed
By the strength of who he eats
This dirted soil as a treat."
Put a few grains of sand in your food and eat it.
