This item first appears to be a Large 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 either up or down. When certain levers are used, the apparatus transforms to resemble a giant lobster. The apparatus of the Crab is a Large object with the following statistics:
Armor Class: 20
Hit Points: 200
Speed: 30 ft., swim 30 ft. (or 0 ft. for both if the legs and tail aren't extended)
Damage Immunities: poison, psychic
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 per minute from pressure.
A creature in the compartment can use an 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 the Crab Levers table.
