Wondrous Item, Legendary
This item first appears to be a sealed iron barrel weighing 500 pounds. The barrel has a hidden catch, which can be found with a successful DC 20 Intelligence (Investigation) check. Releasing the catch unlocks a hatch at one end of the barrel, allowing two Medium or smaller creatures to crawl inside. Ten levers are set in a row at the far end, each in a neutral position, able to move up or down. When certain levers are used, the apparatus transforms to resemble a giant lobster.
The Apparatus of Kwalish is a Large object with the following statistics: AC 20; HP 200; Speed 30 ft., Swim 30 ft. (or 0 ft. for both if the legs aren’t extended); Immunity to Poison and Psychic damage.
To be used as a vehicle, the apparatus requires one pilot. While the apparatus’s hatch is closed, the compartment is airtight and watertight. The compartment holds enough air for 10 hours of breathing, divided by the number of breathing creatures inside.
The apparatus floats on water. It can also go underwater to a depth of 900 feet. Below that, the vehicle takes 2d6 Bludgeoning damage each minute from pressure.
A creature in the compartment can take a Utilize action to move as many as two of the apparatus’s levers up or down. After each use, a lever goes back to its neutral position. Each lever, from left to right, functions as shown in the Apparatus of Kwalish Levers table.

Each sphere appears in an unoccupied space you can see within 120 feet of you. The spheres last as long as you concentrate (as if concentrating on a spell), up to 1 minute. Each sphere sheds dim light in a 30-foot radius.
As a bonus action, you can move each sphere up to 30 feet, but no farther than 120 feet away from you. When a creature other than you comes within 5 feet of a sphere, the sphere discharges lightning at that creature and disappears. That creature must make a DC 15 Dexterity saving throw. On a failed save, the creature takes lightning damage based on the number of spheres you created.
Spheres Lightning Damage
4 - 2d4
3 - 2d6
2 - 5d4
1 - 4d12

Once it is activated, the mirror gives its information for 1 minute or less, then returns to normal. It can’t be used again until the next dawn.
