Bag of Beholding

A bag made of black dragon scales, and a purple dragon eye. The eye appears to always be watching the nearest person, and cannot be fooled by disguises, or by shape shifting. This bag has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. The bag can hold up to 500 pounds, not exceeding a volume of 64 cubic feet. The bag weighs 15 pounds, regardless of its contents. Retrieving an item from the bag requires an action. The bag cannot be opened by someone who does not own it. If someone who does not own the bag attempts to open it, they must roll a dexterity saving throw. if they succeed, nothing will happen, if they fail, roll a D10.

1. The person will be petrified.
2. The person will take 1D20+2 psychic damage.
3. The person will be knocked prone.
4. The person will be trapped inside.
5. The person will be bitten by the bag, doing 1D4 piercing damage.
6. The person will be knocked unconscious.
7. The bag will "breath" fire at the person, doing 1D10 burning damage.
8. The bag will release a random enemy of the DM's choice to attack the person.
9. The bag will release a random elemental of the DM's choice to attack the person.
10. The bag will release a shockwave, doing 1D20 fire, poison, lightning, thunder, radiant, necrotic, cold, acid, force, and psychic damage.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.

Placing a bag of beholding 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 the 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.
