To make Savior Schapps in Kingdom Come Deliverance 2, you need to bring one Nettle and two Belladonna to an alchemy table to begin the crafting process. Thankfully, unlike other craftables in the game, you get the recipie to make it right at the beggining of the game, as long as you don't ditch the old lady who saved your life from minute one.

Deliverance 2 is by drinking a unique potion called Savior Schnapps, making it hard to preserve your progress often. Due to how limited Savior Schnapps can be, you may want to resort to mods to establish a consistent save system.
