This is a very concentrated banishing powder, and it's known as Exodus Powder because it allegedly stimulates your spell's target to recreate the exodus- a sudden departure.
Sprinkle the Banishing Powder on clothes, especially shoes, belonging to anyone you'd like to see gone
* Sprinkle the powder on the ground, so that the target of your spell is forced to step on or over it
* Banishing Powder will enhance the power of any other banishing spell.
Sprinkle as an accompaniment, particularly around and over candles
