An orb of blueish purple haze is surrounded by concentric rings. When you come near it the rings begin to spin and the interior nebula begin to turn and flow. 

You must make a DC 20 charisma safe. On a success you take 3d6 psychic damage. On a fail you cast a random divination spell or whichever the DM chooses. Afterward you take 1d6 plus additional 1d6 for each level of the spell of psychic damage. So for a 4th level spell you take 5d6 of psychic damage. You may choose to fail the safe.

This item recharges at dawn.
