The Syringe is a Hardmode rogue weapon dropped by The Plaguebringer Goliath. It auto-fires a high velocity syringe that increases damage as it travels and inflicts the Plague debuff. On contact with an enemy or block, it will shatter into glass and plague cinders.
Performing a stealth strike with The Syringe will cause the next syringe thrown to release several plague bees upon shattering.
Its best modifier is Unreal.
