I tried sage, it was pretty fun but its too slow. I love its soul degeneration and amplify damage, aoe purge and the easy way to gain chi(so fun in mass pks) but I went back to demon because I love when I don't need holy path to run away. Demon nova is op, 0 pdef is best xD but like Calypso said its better for you to try what cultivation fits you. Good luck (^_^)
