I just used emp and my cognitive abilities got better. But later on I added wanted and Rebirth but it still continued to improve my cognition
Edit:current stack rebirth zp + emp zp. Three subs are heavy . I tried to do one loop each title and one day rest but I think it was heavy. One two titles per day is manageable . But my logic was two main titles + stacking module but I underestimated rebirth its powerful af
