PSA: you can apply potions (or poisons) to drinking water
I'm posting about this because it took me multiple playthroughs to learn this and I'm so mad I didn't realize it sooner and the game doesn't make it obvious lol.
Ever wonder what all those seemingly useless drinking waters are doing sitting around or being sold for 0.1 groschen? Well they have a use and it's quite OP
You can apply potions (or poisons) to them and doing this has a couple benefits
One potions spikes up to 5 drinking waters effectively giving you a 5 for 1 deal, the effects are not diluted at all. You can use poisoned drinking water to poison food pots for the same effect as well.
When you apply a potion to drinking water it filters out all the alcohol so you get all the effects of the potion without getting drunk. Don't you hate when you use 3 or 4 potions before a tough battle and all of a sudden you're drunk as fuck? Look no further!
It also removes the nourishment so you can use a shitload of potions without becoming overfull
If your potion is stolen, the drinking water it's applied to will not have the stolen tag
The only negative effects of doing this are the spiked drinking water has a value of 0.1 groschen so cant make more money using this method. Also you cannot apply poisoned drinking water to a sword or arrows.
