Magic Item: Bag of Withholding

Acts like a Bag of Holding (actually is a bag of holding which casts phase object on the items, so the timing must be such that you can get the item at the right time). Holds twice the amount of a bag of holding, but has a 50% chance of not returning the item, or returning a random item. This is because the bag of withholding has a Phase Object (insert link) cast on its interior lining. The items phase in and out of the present as they oscillate forward one round and back one round.
