Even the system of boiling and distilling has its roots in what people were actually doing in 1400.
In addition, the majority of the potion recipes have their basis in actual recipes folx would use to try to heal themselves back then. All the plants are real and could be found in Bohemia. Warhorse’s dedication to base the game in history can be seen all throughout the game’s Alchemy and Herbalism systems. Kingdom Come’s attempts to replicate real-world 1400’s Bohemia for its players is what makes the game so unique and many of its “tried-and-true” systems – like potion-making – feel revamped and fresh.
