Powder of the Red Death

All creatures within a 30-foot radius from the point of impact must succeed on a Constitution saving throw (save DC 17) or have the Poisoned condition for the next minute. While Poisoned in this way, a creature immediately begins suffocating. At the end of each of its turns, an affected creature repeats the save at Disadvantage, ending the effects on itself on a success. This crimson powder smells of lavender and burning wood.

Powder: A powder is not consumed or applied, but rather packed in a flask, usually equipped with a fuse. The contents of a powder flask spread upon impact, affecting a small area around it. In order to use them, you must forego one of your attacks and throw the powder up to a range of 20 feet.
