I've been making some mean drain fatigue potions of late! Let me know if you want my secret recipe
Serious question though, if I make a potion that has negative side effects (e.g. I haven't calcinated it well enough

), will I know what they are or does that depend on my alchemy skill? I mean, when you make a potion that does something due to there being two ingredients with that property in the recipe that shows us, but what about just a negative side effect?
