Bag of Annihilation

This bag Is indistinguishable from a bag of holding. The space inside however shares properties with a Sphere of Annihilation.  Any matter placed in the bag is obliterated. Items not fully placed in the bag take 4d10 force damage.  Artifacts cannot be placed into the bag, stopping at the bags threshold.  A DC 15 Strength check can force an Artifact into the bag and causes the bag to rupture.

If the bag is pierced, or torn, it ruptures and is destroyed and everything within 4d10 feet are obliterated, a creature in this space must succeed on a DC18 Dexterity saving throw to avoid being obliterated,  Instead taking 4d10 force damage

If the bag is turned inside out then the GM determines randomly what happens, using the following table

Placing a bag of Annihilation inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Far Realm. 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 Far Realm. The gate then closes. The gate is one-way only and can't be reopened.

-Wizards were once so preoccupied with whether or not they could, they seldom stopped to consider whether they should.
