Notes[ | ]

  • This is one of the first ingredients Geralt learns about when he arrives a Kaer Morhen in the Prologue. It is found in a chest in the evening hall on the second floor.
  • It is necessary for the brewing of A Potion for Triss.
  • Kalkstein buys this mineral.

Exploit[ | ]

  • As long as you don't have calcium equum in your inventory or some lying around on the floor close by, the chest's supply can be endless. Just continue to open and close the chest without removing the contents: with each iteration the total amount of calcium equum in chest will have increased by one. Only remove the contents when you have reached the desired amount.
