Wondrous item, legendary
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 the vessel is opened, roll on the Pyxis of Pandemonium table to determine what happens. Any spells cast by the vessel have a spell save DC of 17. One minute after the vessel is opened, it disappears. It reappears, sealed, in a random location on the same plane of existence 24 hours later.
Curse. Any creature that gains the benefit of a short rest from the vessel hears cloying telepathic whispers emanating it. That creature must make a DC 17 Wisdom saving throw. On a failed save, the creature is charmed by the vessel for 1 hour. The charmed creature does everything it can to open the vessel as soon as possible. On a successful save, the creature is immune to the vessel's whispers for 24 hours.
