A strangely tinkered cube, lined with bleeping servos and inter-tangled wiring. On its prime surface is a large red button, inlaid with the words: "PRESS ME" in Gnomish. The cube is oddly resilient, despite seeming to be quite fragile and light. It was invented by the gnomish inventor Enegrim Ipafiz, renowned for his awkward (and yet highly potent) arcane crafts and workings.
The cube has 3 charges, 1 of which is expended every time the button on its surface is pressed. Whenever the button is pressed, roll a d10, and consult the following table:
1: The cube sparks and malfunctions, sending it haywire. You are teleported to a random location within 100 miles, and to a random plane of existence, chosen by the GM. The cube cannot be used again until it is repaired.
2-3: The cube sends you to the Elemental Plane of Water.
4-5: The cube sends you to the Elemental Plane of Air.
6-7: The cube sends you to the Elemental Plane of Fire.
8-9: The cube sends you to the Elemental Plane of Earth.
10: The cube sends you to any Plane of your choosing, so long as the GM allows.
You remain within the designated Plane of Existence for 5 minutes, before being zapped back into the previous Plane.
