Arcane Puzzlebox

This 4-inch wide puzzle box displays complex runes which change each dawn. The box cannot be destroyed except from a Disintegrate or Wish spell.

Unlocking the box takes 3 hours of uninterrupted concentration, at the end of each hour roll an intelligence check, the DC of which depends on the rarity of the puzzle box. If one of the checks fails the process is interrupted, the box 'Locks' and the puzzle cannot be attempted until it resets at the next dawn. A Knock spell can reduce the number of required checks to 2, but no less than 2. The last person to successfully open the puzzle box 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 can only contain one item no bigger than 5 feet in any dimension and of rarity lower or equal to that of the box, which appears once the box collapses open.
