Sacred Haven of Debauchery

potions, though. Although, yes, towards the end of the game, they restore only a small percentage.

They only restored a pittance for me from the middle of the game onwards, after I got three hundred hit points. Besides, most of the time I had around fifty simple essences, and only a few extracts. You can't heal much with that. And they were useful in battles – otherwise, I would have spent them and been left with nothing. And the healing rune is really great. I used to buy cards, but there weren't that many of them, although I was satisfied with the effect. However, all of this pales in comparison to the fly stings. They are simply overpowered.
The game says that over time, the body gets used to their extract, and they stop healing. Is that true? What is the limit?

I ate three or four hundred black mushrooms, otherwise I wouldn't have had over ninety mana. :)
I also ate apples, but in much smaller quantities.
