Forbidden Oathblade

The Forbidden Oathblade is a craftable Hardmode broadsword that autoswings and is the upgrade of both the Bladecrest Oathsword and the Old Lord Oathsword. When swung, it fires a demonic scythe that collides with terrain and pierces up to two targets. Both the sword and the fired projectiles inflict the On Fire! and Shadowflame debuffs. Critical hits additionally summon purple explosions on the target.
