This 4-inch-wide puzzlebox displays runes which change each dawn. The box cannot be destroyed except from a Disintergrate or Wish spell.
After three hours of uninterrupted concentration, roll 3 consecutive Intelligence checks, the DC of which depends on the rarity of the puzzlebox.
Uncommon: DC 14 Rare: DC 16
Very Rare: DC 18 Legendary: DC 20
If one of the three checks fails, the box "locks" and the puzzle cannot be attempted until it resets at the next dawn. A Knock spell can reduce the number of checks required to 2, but no less than 2. The last people to successfully open a puzzlebox can gain access to it with a touch of their hand. They also receive a mental "alarm" whenever a puzzle attempt fails (provided they are on the same plane).
Each box contains one item no bigger than 5 cubic feet, which appears once the box collapses open.
