As an action, a character can throw this small vial at a point up to 60 feet away. Each creature within 10 feet of that point must succeed on a DC 19 Dexterity saving throw or take 4d10 fire damage and 2d10 piercing damage, half on a pass.

Notes: Green vial that when exposed too much to friction, such as the shattering of the vial, to explode in a deadly fire. There is Scarlet Flow-stone shards inside the liquid, tiny microscopic shards that cut deep into anything around it. The fire is hard to put out without magical means.
