The amulet of the planes is a device which enables
the individual possessing it to transporf himself or herself instantly to or
from any one of the upper levels of the Outer Planes. This travel is
absolutely safe, but until the individual learns the device, transport will be
random. Roll d6, 1-3 = do not add 12, 4-6 = add 12 to d12 for 1-24 random
results:

1-2	Seven Heavens
3	Elysium
4	Happy Hunting Grounds
5	Olympus
6-7	Gladsheim
8	Limbo
9	Pandemonium
10	Abyss
11-12	Tarterus
13	Hades
14	Gehenna
15	Nine Hells
16-17	Acheron
18	Nirvana
19	Arcadia
21-24	Prime Material Plane

You may alternately have the following results:
 

22	Ethereal Plane
23	Astral Plane
24	Prime, but alternate Earth

Question: Are there limitations on the usage of such items as an Amulet of the Planes?
If not, the character can merely speak a command word and blink out to his own alignment plane any time, right?

Answer: Amulets are powerful, arcane devices that are designed to
be used over and over again. Because of their great power, there
should not be many of them running around (one to a universal plane
is enough). The action of running to another plane for safety is risky,
when you consider that the other planes are populated by powerful
beings who resent intrusion! — JW
