This bag has an interior space considerably larger than its outside dimensions, roughly 3 feet in diameter at the mouth and 8 feet deep. The backpack can hold up to 600 pounds, not exceeding a volume of 80 cubic feet. The bag weighs 20 pounds, regardless of its contents. Retrieving an item from the bag requires an action.
This backpack can not be damaged by normal means, is fireproof, and is unable to be ripped, shredded, or damaged by acid. If the backpack is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Sadly one can not put creatures inside the backpack, as it will instantly begin to suffocate them.
Placing a backpack of storage inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can’t be reopened.
Notes: Utility, Container
