i'm know when we eat this item, we can get extra 9 VIT in 1200000 second right? but if we eat 2 (this item) in same time or we eat something like same Soup ex (+8 VIT) this item stack with another or not? it mean when i'm eat this item 2 time in same time i'm press this soup i can get +9 x 2 = +18 VIT or just get +9 VIT only .. i'm hope you understand what i'm explain ..
Second question if i'm die in this soup status, i'm still can get this bonus in 33 minutes or not like bersek potion?
