This bag is marked with strange symbols on one side and feels as if it is made with the finest silk. The bag weighs 5 pounds.
Looking inside the bag reveals nothing, you only see an empty bag.
Reaching inside the bag, you also feel nothing, but when you remove your hand from the bag, an object or creature randomly chosen from the table below is in your hand (in the case of a creature, the creature falls to the ground, prone and unaware of its surroundings).
Placing an object in the bag results in the bag beginning to shake violently and fall to the ground, then spit the object back out.
If another object (or the same one) is attempted to be placed in the bag a second time within a tenday, the bag shakes even more, hitting anyone within 5 ft of the bag for 1d4 bludgeoning damage, and again the bag spits the object out.
If another object (or the same one) is placed in the bag a third time within a tenday of the second attempt, the bag devours the object, sending into a void disappearing from existence and the bag cannot again be used for a tenday. Any additional attempts to store an object in the bag results in this again, resetting the countdown back to another tenday before its next use.
Once per day, as an action, someone can reach into the bag and remove something from it (roll 1d10,000 and use the table below to determine what is removed from the bag). Anything removed from the bag is permanent to the plane, it will not disappear after a time limit -- it is just like any other item or creature on the plane.
A creature removed is prone and immediately hostile (as it is scared and confused), but may potentially be persuaded to be friendly (depending on the creature).
