Campaign of the Month: January 2017
Bag of Lies
This appears to be a common leather sack about 2 feet by 4 feet in size. The bag opens into a nondimensional space: its inside is larger than its outside dimensions. Regardless of what is put into the bag, it weighs a fixed amount. This bag weighs 25 lbs. and may contain up to 500 lbs.or 70 cubic ft.
The bag is protected by a powerful, permanent illusion spell. When opened, it appears to have assorted adventuring gear (a coil of hempen rope, hammer and pitons, lantern, a sack of rations, etc). As long as a real set of those particular items remain in the bag, anyone reaching into the bag may pull out such an item, and the illusion will alter as if the item was removed. The image will reflect when the item is returned to the bag. Otherwise, one must know what is in the bag in order to remove any other item stored within (or upend the bag, spilling its contents.
If the bag is overloaded, or if sharp objects pierce it (from inside or outside), the bag immediately ruptures and is ruined, and all contents are lost forever. If a bag is turned inside out, all of its contents spill out, unharmed, but the bag must be put right before it can be used again. If living creatures are placed within the bag, they can survive for up to 10 minutes, after which time they suffocate. Retrieving a specific item from the bag is a move action, unless the bag contains more than an ordinary backpack would hold, in which case retrieving a specific item is a full-round action. Magic items placed inside the bag do not offer any benefit to the character carrying the bag.
If the bag is placed within a portable hole, a rift to the Astral Plane is torn in the space: bag and hole alike are sucked into the void and forever lost. If a portable hole is placed within a bag of holding, it opens a gate to the Astral Plane: the hole, the bag, and any creatures within a 10-foot radius are drawn there, destroying the portable hole and bag of holding in the process.
The original owner had this item specifically crafted for him because he was tired of pickpockets reaching into his former bag of holding and stealing his stuff. Unfortunately, one such thief stole the whole bag and upended it, taking everything contained within. He later ran into rough times and had to sell the bag buy his way out of trouble.
