This sticky, adhesive fluid ignites when exposed to air. As an Action, you can throw this flask up to 20 feet, shattering it 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.
