Manablade 1

"It's called a manablade," Paldor said when Jace remained silent. "A rare weapon, acquired by Tezzeret some years ago from the Church of the Incarnate Soul."

    "Never heard of them."

    "Not surprising, and also not the point. The blade doesn't just draw blood, Jace. Oh, when used against someone like me, it's normal enough. A knife is a knife is a knife, right? But," he continued, leaning forward, "it cuts into a mage's soul. Bleeds his very essence into the aether. Wound a caster with this, and he doesn't just lose blood, he loses his bonds to mana. I'm told it's just about the most excruciating experience imaginable."
