Crystal Thrum, a distinctive Glintstone Sorcery emanating from the hallowed halls of the Academy of Raya Lucaria.

This enchantment empowers the ferrule of the caster's staff with magic, enabling a forceful thrust into the ground, subsequently generating a potent magical shockwave.

A unique feature of this sorcery is the allowance for a follow-up attack.

Originally a Stonedigger sorcery utilized by glintstone miners in the crystal tunnel, the use of Crystal Thrum within the academy carried a stigmatizing aura, often branding its practitioners as failed scholars.

Navigate through the mine, utilizing an elevator to descend and passing through wooden beams as you venture deeper into the subterranean depths.

By successfully uncovering Crystal Thrum in the heart of the crystal tunnel, you add a potent and stigmatized glintstone sorcery to your repertoire, gaining insights into the diverse applications of magic within the illustrious academy.
