Impossible Tar wondrous, uncommon

This large barrel is full of a sticky substance that is intensely black and viscous. If the barrel breaks or you tip it over the substance oozes forth. The barrel weighs 10 pounds per remaining square it can cover. It takes 1 minute to cover a 5 foot square without touching the tar and it and can cover up to 20 squares. Squares covered by Impossible Tar are considered difficult terrain. 
Additionally, any creature that enters, or ends their turn on, a square covered in Impossible Tar must make a DC 10 Strength saving throw or be Restrained. A creature restrained in this way can use its action to make a DC 14 Strength check and on a success it frees itself.  If a creature becomes Prone while Restrained by Impossible Tar it can not free itself, it must be assisted by another creature.
The tar lasts for one week outside the barrel, until it is frozen, or exposed to universal solvent. It is too sticky to put back in the barrel.
