This adhesive liquid ignites upon exposure to air. As an action, you can throw this flask up to 4 sqr. (6m), where it shatters on impact. Make a ranged attack against a creature or object, treating the alchemist’s fire as an improvised weapon. On a hit, the target takes 1d4 fire damage at the start of each of its turns. A creature can end this damage by using its action to make a DC 10 Dexterity (Sleight of Hand) check to extinguish the flames.
