Goo Bomb

A very sticky and gooey liquid. 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 Goo Bomb as an
improvised weapon. On a hit, the target's
movement is halved. A creature can end this
effect by using its action to make a DC 10
Strength check to break free.
Ingredients: Gooey Substance (i.e. Spider Web),
Water, Flask
