Right now mentioned potions increase a given attribute by several points and it begins to drop almost immediately after drinking.
What it means for me is that virtually only potions of boost speed are of any real value and only when drunk in batches of 3-4.
All other attribute boosts last too short to be of any use.
I don't know about other players, perhaps people find them more useful in more constrained situations with limited resources.
That extra 5-7 toughness and strength might make a difference. Once or maybe twice, but that's it.
I tend to build up a character rather than going head on and barely making it out alive and thus those potions are completely useless to me.
The last time I remember I used any of them was when I tried to build an archmage and needed just a few points of hp and pp more and so I drank all potions of boost mana and boost toughness that I had.
I'm wondering what are the thoughts of other players as I wanted to make an RFE to buff the potions a little bit - make them last a bit longer, give a slightly bigger increase and begin dropping to default values several dozen turns later.
After all, they are possibly as rare as potions of attributes and so won't be able to grant their bonuses too often.
