Pyxis Of Pandemonium (Chained)

Wondrous item, legendary

This ornate wooden chest is wrapped in red chains, with a large padlock with no keyhole. It cannot be opened without removing the chains.

A creature that touches this ornate wooden vessel for 1 minute gains the benefits of a short rest. That creature also gains the effects of the bless spell until the creature finishes a short or long rest. The creature can’t gain these benefits again until it finishes a long rest.

If a creature holds the chest for a full short rest, they attune to it, allowing them to raise one ability score by 2, to a maximum of 30. The Pyxis then loses this ability for a century.
