Rubedo

[Vigo]

I need help to find the Rubedo formula, I searched every single location I found online, looked at every sinlge wiki page about it both in french and english, and none of them had the bloody formula. So, considering I don't have acess to the master alchemist yet, any of you lads know where I could find what I'm looking for?

Alchemy recipes are random. Some chests may have or not chances to give an alchemy recipe. If a said chest has chances and gives a recipe then that recipe is sorted out from 2 groups of alchemy recipes. One of the groups is for recipes that can be obtained any moment, the second group is for alchemy recipes that can only be obtained after you have unlocked access to Skellige map.
