Magic Sapphires are the Magic Stones that you create when using Owl Magic. 


To generate Magic Sapphires, you need to activate the Apprentice Hat by playing 5 cards in a row. 


When the hat is activated, it creates a Magic Sapphire for each additional card you play in a row until you draw a new card.


To complete the challenge "Generate X Magic Sapphires",  activate your Apprentice Hat, then play as many cards in a row as you can before drawing a new card. You must create a total of X Magic Sapphires to complete this challenge!
