The Golden Cage
Bag of Holding Type I
A small sack enchanted to contain an extradimensional pocket of space.
This appears to be a common cloth sack about 1 foot by 6 inches in size. The bag of holding 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 weight, and the limits in weight and volume of the bag’s contents, depend on the bag’s type. A type I bag of holding weighs 15 pounds, contains 250 pounds of weight at its limit, and contains 30 cubic feet of space.
If a bag of holding 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 of holding 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 a bag of holding 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 a bag of holding 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.
