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, 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.
