The Crown of Natal Jubilee
A mythical item that legend has said appears when a soul reaches a new age. Most believe this to be a fallacy, as the item does not appear for most. The story claims that once the cap chooses a holder, there is a higher chance it will appear for the holder's companions in the future.
Once it appears, the myth tells of incredible properties when worn, and within 24 hours of its appearance, it is said to disappear just as silently as it arrived.
The holder of this cap can create one of the following Effects of their choice (per charge):
• You create one object of up to 1,000 gp in value that isn’t a magic item. The object can be no more than 100 feet in any dimension, and it appears in an unoccupied space you can see on the ground.
• You allow up to three creatures that you can see to regain all hit points, and you end all Effects on them.
• You grant up to two creatures that you can see resistance to a damage type you choose.
• You grant up to two creatures you can see immunity to a single spell or other magical effect for 4 hours. For instance, you could make yourself and a companion immune to a lich’s life drain attack.
• You undo a single recent event by forcing a reroll of any roll made within the last round (including your last turn). Reality reshapes itself to accommodate the new result. For example, you could undo an opponent’s successful save, a foe’s critical hit, or a friend’s failed save. You can force the reroll to be made with advantage or disadvantage, and you can choose whether to use the reroll or the original roll.
