The Knowledge Gem is an item that debuted in Three Houses. It is classified as equipment, alongside staves and shields.

Effect[]

When equipped, the Knowledge Gem will increase any skill experience and class mastery experience that its holder gains in battle. Specifically, it doubles class mastery experience and doubles skill experience gained before adding bonus skill EXP for belonging to a class. This includes a character’s strengths and weaknesses. The Knowledge Gem does not affect skill experience gained from non-combative activities such as tutoring. The class mastery experience boost 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).

Additionally, Lysithea and Jeritza are able to compound these effects once more thanks to their Mastermind skill, although the latter will need to sacrifice an ability slot in order to do so.
