Thanks! Glad you like it! Currently the potion recipes are:
Erb Herb + Rue Root = Health Potion
Erb Herb + Werewolf Bane= Ether
Erb Herb + Root + Werewolf Bane = Elixer
Monster Eye + Mandrake = Sleep Potion
Monster Eye + Crow Feather = Poison
Erb Herb + Crow Feather + Knight Shade = Antidote
(There was a strength potion for the character trying to get strong but I guess it's bugged rn :< )
