It's not necessary to do them both at the same time but most readers do it. It is powerful but I don't think it will overpower your POI. You will just be on their mind constantly. :-)
Hello! I have been using PW for a few days and it started working. I also decided to add the love spell to make it even stronger. Is it okay the days I do the love spell to also do PW everyday? Can the two work together well or it can be too much for the POI? Thanks!
