The True Forbidden Oathblade is a craftable Hardmode broadsword that autoswings and is the upgrade to the Forbidden Oathblade. When swung, it will fire 3 demonic scythes that collide with terrain and pierce up to two targets, each dealing 50% of the blade's damage. Both the sword and the fired projectiles inflict the On Fire! and Shadowflame debuffs. Critical hits additionally summon purple explosions on the target.

Its best modifier is Legendary.
