GURPS - Compendium 1..

World-Jumper
Variable
This is the power to travel to a parallel world without
machinery or a gate -just by willing the "jump." The basic cost
of this power is 100 character points, but modifications to the
ability (described below) can vary the cost.
This advantage can be improved with time and practice.
Someone who starts with World-Jumper ability can spend character
points to improve the power at a later date, removing limitations
or increasing the weight that can be carried.
Making the Jump
To visit another world, the Jumper must visualize it for ten
seconds and make an IQ roll, rolling against his "memory" of the
world. On a successful roll, the Jumper appears in the new world
(see below). On a failed roll, he does not move, but may try
again. A critical failure sends the Jumper to the wrong world!
This is terribly dangerous, of course, but if the Jumper survives, he
may find that he has sole access to a newly-discovered world.
To be visited repeatedly, a world must be "memorized."
Memorizing a world is a Mental/Easy task; thus, learning a new
world at IQ level costs 1 character point. A Jumper can accomplish
this "memorization" in one undisturbed hour absorbing the
"feel" of the new world. (If a Jumper visits a world and does not
memorize it, he can try to return anyway, but he rolls at IQ-3.)
Unless a Jumper wants to be sure of hitting his target world
immediately, there is little need to put extra points into memorizing
any one world. Should a Jumper choose to do so, each
additional point spent takes one additional hour.
Normally, for a Jumper to visit a new world for the first time, he
must be "escort ed" by another Jumper. The two (or more) must
be in physical contact; each may carry his normal load. The
"lead" Jumper makes the IQ roll. All the other Jumpers go along
automatically. "Escorting" can be involuntary! If two Jumpers
are in physical contact when one of them jumps, and the other
one wishes to tag along, he will. Of course, in a campaign where
other methods of cross-world travel exist, a Jumper may use them
as well.
Some Jumpers have enhanced abilities (see below) which let
them visit new worlds. Other new worlds are discovered by
accident, when a Jumper goes to the wrong place and survives.
The "Landing"
The Jumper appears in the new world at exactly the same
place he left the old one, or as close as possible. This works
exactly as for Time-Jumper - see p. 46. There are a few
instances in which world-jumping is more flexible than timejumping.
You could world-jump while on a transcontinental
flight, if your target world was so nearly identical that there was a
plane in the same place!
Fatigue Cost
The Fatigue cost of a world-jump depends on the "separation"
of the two worlds; see p. TT87. For those without access
to GURPS Time Travel, assume that the normal Fatigue cost is
from 1 up to 10 if the worlds are very "distant."
Load Carried
Treat this exactly as for Time-Jumper, p. 46.
Special Limitations
Some Jumpers have particular limitations on their powers,
which reduce the character point cost. The GM may permit
other limitations (for ideas, see Chapter 4), setting their costs as
appropriate. Minimum cost for this ability is 60 points. Some
known limitations are:
Cannot escort another Jumper. If this character ever
learns a new world, he won't be able to take others there. -10
points.
Cannot follow another Jumper. This is a more severe limitation,
because it drastically cuts down on the Jumper's opportunities
to learn new worlds. -20 points.
Drift: As for Time-Jumper, p. 47. -15 points.
Stunning: The Jumper is always mentally stunned after a
jump. -10 points.
Uncontrollable: As for Time-Jumper, p. 47. -10 points.
Special Enhancements
A few Jumpers have extra abilities, which increase the character
point cost. Some known enhancements are:
New worlds. The Jumper can deliberately aim for worlds
where he has never been. Any such attempt is at IQ-3, with a
further penalty assessed by the GM, depending on how different
the world is from anything in the Jumper's previous
experience. Of course, it is always possible that no such
world exists, depending on the number of parallel worlds in
the campaign. In that case, any attempt automatically fails,
although the Jumper won't know why. Fatigue cost for any
attempt to hit a new world is twice normal. (The GM who
finds this enhancement too powerful is free to forbid it!) +50
points.
No concentration required. When you want to jump, just
make your IQ roll. +75 points.
Reduced fatigue. Visiting most worlds costs no Fatigue; dis tant
worlds cost only 5. +20 points.
Teleport jump. As for Time-Jumper, p. 47.
Tracking. The Jumper can visit a world where he has never
been, if he can hold and examine an artifact from that world.
The attempt must be made while the Jumper is holding the artifact
(or touching it, if it's too big to carry). Any such attempt is at IQ-
2, and each Jumper only gets one try per artifact. +20 points.
World Sight
10 points
You are able to perform shamanistic magics (see pp. R116-
125). You have the ability to transcend ordinary human limitations
and gain the power to enter the domain of gods and spirits.
You may be subject to intermittent visions even if you never
receive proper training as a shaman.
