Bag of Smells

When opened, this bag releases a faint but pleasant scent, like a freshly baked pie. Upon smelling the bag, the one who smells it must make a wisdom saving throw, DC 14. On a success, nothing happens. On a failure, the user is compelled to continue smelling the bag as the scent gets worse, and make another wisdom saving throw, DC 16. On a success, the holder is free of the compelling nature of the bag. On a failure, the user is once again compelled to continue smelling the now putrid smelling bag, and make another wisdom saving throw, DC 18. If the holder fails third saving throw, they must make a constitution saving throw, DC 18, and become poisoned on a failure.
