The Dementia Potion is an Item in Kingdom Come: Deliverance and can be made with Alchemy.


He who drinks of this potion shall become dull-witted and be regarded as a fool, for even an ass brays more intelligibly than one who has drunk thistle in wine and then tries to hold wise speech with others.


Greatly reduces speech.


  • You will need wine, a handful of sage and two of thistle
  • Grind the sage
  • Throw the thistle in the cauldron and boil for one turn
  • Add the sage and boil for one turn
  • Distil.
