Bag of doom

This was once a terrible item gifted to the humans by a devil designed so any object placed inside it then belonged to the devil and when they tried to remove it it exploded. When the humans realised they hunted the devil and killed him. The enchantment lost a lot of its power and the explosion created is less drastic. Anyone other than the owner of items placed inside the bag must succeed a dc12 dexterity check or take 1d6 force damage. Also the bag screams when an item is removed by anyone other than the owner
