Jade, powdered (bag)

Collected dust from a workshop that polishes and sets jade. As an action, you can pour out the powder to draw a line across three adjacent squares. 

Alternately, you can spend an action to throw a handful at a creature within 5 feet of you. Make a ranged attack against a target creature or object, treating the dust as an improvised weapon. On a hit, if the target is an aberration it takes 2d6 radiant damage.

The bag has sufficient dust for ten uses – ten thrown handfuls, 150-ft. worth of lines, or some combination.
