I’ve only done one blood pact, about 5 years ago. Kind of funny that Mundopincha mentioned a fingerprint because looking back on it now I guess that’s what I did without realizing it. I wrote the pact out on paper and signed it in ink, then cut my finger and pressed it against my signature, it did leave a finger print, though that wasn’t my intention at the time but it does make sense after reading this.
I do have to say, looking back now, that the results were pretty intense. It was to better my life because I was pretty much an outlaw; plus I was in a terrible marriage as well. Ended up getting a killer legitimate job (killer due to the possability for advancement, started out mowing lawns for company housing), though my life went to shit aside from the job. Everything went upside down and backwards, after 2 years of disaster and divorce, I ended up with an amazing woman (got the ring, about to propose next week) and getting payed a lot of money at a leagal/hard working job as a machinist at the compant I became employed at during this period (I now contribute to my “outlaw” MC through charity bike runs, 30k of which was donated to the hospital that saved my son’s life last year, he had an infection seeping into his briain).
A blood pact can seem to take you through hell (mine did), but when its over all the pieces fall where they need to be to make you better. Not sure if your experience will be the same, just thought I’d share mine. My pact was with the god Set (chaos, storms, change, evolution), that may have made mine more intense, not sure. Good luck to your’s, mine was well worth it.
Long story short:) I don’t really think the application of the blood really matters as long as the intent and terms of the pact (and goal you wish to achive) are there when you give the blood. But from my experience it’s worth the short term turmoil.
