A blood-filled vial is an item used in Herblore to create evil potions. To get a blood-filled vial, you need to attack a player using a syrinx while having an empty vial in your inventory. However the vial will only be filled if you hit a 50 or more. Hitting a 100 will fill 2 vials, a 150 will fill 3, etc.

Blood-filled vials can be emptied by right clicking and selecting "empty blood-filled vial".
