The Drive Blade is the favored weapon of the Imperial Class in Etrian Odyssey IV: Legends of the Titan. It is a heavy, 2-handed weapon with a powerful motor built into the blade and the ability to utilize cartridges to boost its damage output or allow for elemental strikes. Though the weapon itself cannot be used alongside other weapons, owing to its requiring two hands to wield, it is fully compatible with sword techniques used by the Landsknecht and Nightseeker classes, it does more damage than a conventional blade, and its unique ability to engage its drive motor can make it far more powerful than any conventional weapon has any right to be.
