The Five Treasures

After refusing to accept the dark bargains offered by the god Nazeth, the party was whisked from his dimension by avatars of the deities Valakesh, Mellavine, Shial, and Ezrammel, and were each given one of five treasures representing the desire of the Yntherian gods to thwart Kathax's attempt to seize dominion over the plane.

Rod of Power
One of five treasures given to Noren. It is a plain wooden rod, carved with runic symbols, which has at one end a heatless candle flame which burns until the item is used, and flickers back into being when the item is recharged. It is associated with the god of knowledge Ezrammel.

The energy from the ley-line overcharge flooded this item, changing the runic symbols on the rod and altering its properties. The rod allows the user to refresh one expended spell slot of 3rd level or lower per long rest. It must be attuned to the user in order to function.

Periapt of Wound Closure
This is what Bastian got. Sure would be nice if we knew what it did. It was once a whoozit, not to be confused with a whatzit.

Boots of the Zephyr
Given to Jessa. It is a pair of winged boots. The wearer receives a flying speed equal to their walking speed. They can use the boots to fly for up to 4 hours, all at once or in several shorter flights, each one using a minimum of 1 minute from the duration. If in flight while the duration expires, the wearer descends at a rate of 30 feet per round.

The boots regain 2 hours of flying for every 12 hours they're not in use.
