I witnessed something weird today. I changed mains from fire main to wind main and back and changed nothing to my power items and to my surprise my P1 ninja got a buff in Life while being fire main (92 606 being my Life then) and when I changed back to wind main my Life was 92 467. What happened? How this could be explained. I can think of mains cultivation system. My fire main has all of his skills fully cultivated while my Wind Main none.
