Tanglefoot bag

Unguents and adhesives fill this airtight sack. You can use an action to throw this bag at a target within 20 feet, treating it as a ranged weapon attack with an improvised weapon. On a hit, rapidly hardening sap covers the target and it makes a DC 13 Strength check or becomes grappled. At the start of each of its turns, the target repeats the check, ending the effect on itself on a success. The sap can also be destroyed (AC 13, 6 hit points).
