Mmmostly?

The sample Blood Sorceries in the 2e core were designed using Sacraments and Blasphemies as a partial reference IIRC, so with a couple tweaks for things like time per roll and Experience cost per dot of a Theme they should work basically fine. Ooon that note of intervals though, I don't have my books up right now but I'm 99% sure 2e sorceries use much longer intervals than S&B did... it'd probably be good to change one or the other for consistency's sake, or change both to somewhere between the two if you feel one interval or the other would be too fast or too slow.
