If you can find a book called "Gypsy sorcery and fortune telling",it has several chapters full of incantations,and the book is quite old,and they've reprinted it,i would tell you where i downloaded it,but,i think the person who made that website shut it down,i'm sure if you look around you'll be able to find it,you might try darkbookz.org.
I am a sorceress of the ancestral magic. I could develop your found skills in adapting the wisdom more but it would need you to gather your commitment and your desire in achieving the effects you are wanting. Being one with the ancestral magic is not as easy as it seems. You need to maintain your mentality for as you dwell deeper on incantations, all and every part of your body will be affected by the spell as well.
