Portable Hole
You can use an action to unfold the _portable hole_ on a stable solid surface. When unfolded, the item creates a hole 10 feet deep that leads to a cylindrical extra dimensional space which cannot be used to create open passages. Closing the hole requires an action and involves you taking a hold of the edges and folding it up. No matter its contents, the hole weighs next to nothing.
Food or water placed in a closed _portable hole_ immediately and permanently lose all nourishing qualities—after being in the item, water no longer slakes thirst and food does not sate hunger or nourish. In a similar fashion, the body of a dead creature placed in the portable hole cannot be restored to life by __revivify , raise dead_ , or other similar magic. Breathing creatures inside a closed _portable hole_ can survive for up to 2d4 minutes divided by the number of creatures (minimum 1 minute), after which time they begin to _suffocate_ .
Creatures inside the hole while it’s open can exit the hole by simply climbing out. A creature still within the hole can use an action to make a DC 10 Strength check to escape as it is being closed. On a success, the creature appears within 5 feet of the item or creature carrying it.
Placing a _portable hole_ inside another extradimensional storage device such as a _bag of holding_ or __handy haversack_ results in planar rift that destroys both items and pulls everything within 10 feet into the Astral Plane. The rift then closes and disappears.
