Arcane Lock Boxes and Puzzle Boxes

Created by the council to test if a person is capable of magic an arcane lock box usually contains a magic item depending on how difficult it is to open. The council based the puzzle boxes on the sketches in Yarin Moto's journal and his own puzzle box. The council puzzle boxes will almost always have nothing in them bar a harder puzzle box inside to test the trainee more.  

Stats

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.   After 3 hours of uninterrupted concentration, roll 3 consecutive intelligence checks the DC of which depends on the rarity of the puzzle box:   Uncommon: DC 12 Rare: DC 14 Very Rare: DC 16 Legendary: DC 18 Councilman: DC 20   If one of the three checks fail, 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 puzzle box can gain access to it with a touch of their hand they also recieve a mental 'Alarm' whenever a puzzle attempt fails (Provided they are on the same plane).   Each box contains only one item no bigger than 5 cubic feet, which appears once the box collapses open.  

Arcane Puzzle Boxes

A variant of arcane lock boxes these were made to as a way to pass to time and for fun. Puzzle boxes do not hold items but every time they are solved they become harder and harder until they are solved and you either rest it, turn it into a lock box or buy a new one. Puzzle boxes start of at DC 10 and increase by 1 every time it is solved.
