The Knowledge Gem is an item that debuted in Three Houses. It is classified as equipment, alongside staves and shields.
When equipped, the Knowledge Gem will double any skill experience and class mastery experience gained in battle, but this does not affect skill experience gained from activities such as tutoring. This will stack when the player upgrades the statue of Cethleann, effectively quadrupling the amount of experience gained when mastering a class (though skill experience remains at being doubled).
