The Seven Sins is a Hardmode bow that can be dropped from Infernon. On every 5th arrow fired, it summons a Fire Lash projectile attached to a chain that protrudes from the bow at short distance quickly, then comes back. The Fire Lash can pierce many enemies, going forward and coming back. When an enemy is hit by the Lash head, it will inflict the Combustion Blaze debuff upon contact.
Its best modifier is Unreal.
