Hello, thank you for your input!
>I feel like clairvoyance potions should counteract the vision-reducing effects of fog.
That is a cool idea. It fits the flavour. I will probably make it that way.
>Why can’t I get “Something toxic” from fiend’s powderbox mushrooms? Given their effects in-game, I would think they would be a potent source of it.
They used to give that, but I changed it to something sinister at one point for more usefulness, as something toxic is abundant anyway. Now that I think of it, though, I can just make both options available.
>Some way to “unequip” potions from the throw action would be nice.
I never considered that it would be useful, but implementing it won't take long, so I will.
>I think it would be useful if there were some way to remove locations from the list once you no longer intend to visit them.
I will need to think of such a feature.
>I feel like all the mid-game research is all bunched up on the third row of the tech tree, and it would be better (both for readability and progression) if the third row were split into 2 rows, resulting in 2 rows for early-game research, 2 for mid-game, and 2 for late-game.
What is currently a late game won't be for very long, and specifics of the research tree, too, will be subject to change.
>I think it would be interesting if there was some way to “transmute” one alchemical ingredient into another
Something like alchemical gold is a possibility, but I don't have any specific thoughts yet.
