On an older version of Botania, rolling a 2 on the Dice of Fate would grant a Holy Sword Excalibur. This was later changed to give a Key of the King's Law. However, the mod Plants adds a recipe to change the Key of the King's Law into a Holy Sword Excalibur. I made the Excalibur, and then killed the Gaia to reobtain another Key of the King's Law. Unfortunately as my character has already obtained a Key of the King's Law, I was not able to get another one. I was sure to check I landed on the right side with the dice, but nothing happened and my Key of the King's Law is gone.
