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


let ur current stack shine
so QL still has some of it and manifesting for you guys cheers
" makes them stackable.
