I thought it would be obivious but its not, I have the pestal and mortal and empty flasks and reagents, ive tryed all kinds of ways to combine , add ect, but nothing happens!
I did a search on the forums but too many pages came up with "potion" and none were related to what I needed to know!

Thanks for any help on this!

1. Right click mortar
2. Put an empty flask into popped up slots
3. Put an accurate number of needed reagents (to pick up 1 piece of reagent from stack shift+left click it)
4. A potion appears in the slot below
5. Pick up a potion and move it into inventory

No idea where to post it otherwise...

Theres a way to create a Poignant potion too? i first saw the poignant potion in one of the mods, but i never thought it was possible to make one. I tried the poignant potion, but got poisoned
