Aura Strong conjuration CL 17th

Price 200,000 gp Weight 1,000 lb.

A tumbler is an odd vehicle. It looks like a large sphere of rough-hewn rock, with a seam that breaks a surface covered in dull stony spines. When a tumbler is open to accept or debark passengers, one can see seats within for up to twelve human-sized or smaller creatures.

The tumbler rolls when in motion across the ground, but a magic stabilization device built into the vessel keeps its occupants level as it goes. In addition, a ring of clear crystal windows are set into the sides of the sphere, fixed according to the perspective of the passengers. These windows prevent disorientation, allows the pilot of the vessel to see out, and lets passengers know where they are.

A tumbler can move at a constant speed of 10 miles per hour across level ground, even that considered difficult terrain. However, the vessel’s most unique power is its ability to move through the earth like the earth elemental bound into it. The tumbler in this mode can glide through stone or dirt (though not metal) as easily as a fish swims through water, at a speed of 2 miles per hour. The vessel’s burrowing leaves behind no tunnel or hole, nor does it create any ripple or other signs of its presence. A tumbler can carry twelve Medium or smaller creatures, including the pilot. The passengers sit in a stacked row of seats, six on the bottom and six on the top (the pilot sits in the upper row).

The tumbler magically refreshes the air supply within it, allowing twelve Medium creatures to breathe comfortably for ten days. If the tumbler spends at least 1 hour in the open air (whether aboveground or in a large cavern), this time limit is reset.

A move earth spell cast on an area containing a tumbler flings it back 30 feet, deals 4d6 points of damage to those inside (no save), and renders the craft powerless for 1 minute.

Operation: A pilot can operate a tumbler aboveground with a successful DC 20 Profession (pilot) check, but piloting the vessel beneath the surface requires even greater expertise. A pilot must make a DC 25 Profession (pilot) check to activate the vessel’s earth glide mode. The pilot navigates by means of instruments inside the vessel, and knowing how to decipher these devices is quite difficult.


Requirements Bind Elemental, greater planar binding.

Cost 100,000 gp


The tumbler was initially developed by the gnomes of Zilargo to aid in mining expeditions. Rumor has it that the gnomes have since begun selling the vessel in limited numbers to various governments across Khorvaire for use in espionage, because its burrowing power makes it easy for spies or squads of elite troops to sneak into places they shouldn’t.
