Cursing the 72 names of the "god".
This one is very powerful and can be done whenever you want.
Genesis 11:9 - Ending confusion
This one I have found to be very useful, due to Gentiles still not being able to completely see through mist that is due to this curse. For example, I've seen people who are awakened to the kike evil, but they say that "(these are not real jews, and that these are of "Synagogue of Satan") or similar nonsense. Confusion brought by this curse.
It is stated on JoS site that RTRs can be done whenever you have free times, and whenever you feel angry towards enemy. So, go and hit 'em hard!
