Vial of Lyrium

As an action, you can splash the contents of this vial onto a creature within 5 ft. of you or throw the vial up to 20 ft., shattering it on impact. In either case, make a ranged Attack against a creature or object, treating the vial as an improvised weapon. On a hit, the target takes 4d6 acid damage and make a Constitution Saving Throw DC 11, or develop the first stage of Lyrium Craze.
