Fixed Magic
Fixed magic is the ability to cast a
spell without consciously knowing it.
It represents, for example, the instinc-
tive magic of certain animals in some
fantasy worlds. Such abilities form a
class of meta-traits. Each meta-trait
has three components, as follows:
First, choose the desired spell, and
list all of its prerequisites, and all of
their prerequisites, back to a set of
spells without prerequisites. If more
than one list is possible, choose one –
normally the shortest, but this isn’t
obligatory. There is a cost of 1 point
per spell in the chain of prerequisites.
Second, identify the highest level of
Magery required for the spell or any of
its prerequisites. Buy that level of
Magery, with the modifier One Spell
Only (p. 129). In settings with normal
or low mana, Magery 0 is the mini-
mum; in settings with high or very
high mana, it may not be required for
all spells.
Third, determine the cost of learn-
ing the spell at the desired level, given
the user’s IQ and Magery. A campaign
setting that uses fixed magic may have
a standard level of ability for all spells,
at the GM’s discretion.
For example, an army wound
dresser with IQ 11 would find it useful
to be able to heal wounds. The spell
Minor Healing has the prerequisite
chain Lend Health, Lend Energy; two
prerequisites cost 2 points. Lend
Energy requires Magery 1, which
costs 5 points for Magery 0 and 2
points for Magery 1 (One Spell Only,
-80%). With IQ + Magery equal to 12
he would pay 4 points to learn Minor
Healing-12. Total cost is 2 + 5 + 2 + 4
= 13 points. This enables him to repair
1 to 3 points of injury at an energy cost
of 1 per point, just as if he had learned
the spell. He can’t use Lend Health or
Lend Energy, and he can’t improve his
Minor Healing ability by further study.
What he knows is a fixed pattern of
actions, the magical equivalent of a
reflex.
This system can be used for more
than one spell. Buy the required level
of Magery once, with a reduced limita-
tion (p. 129); buy each spell separately
at the desired level. If one fixed spell is
actually in another fixed spell’s prereq-
uisite chain, count only the additional
prerequisites for the second spell. But
if neither spell is in the other’s prereq-
uisite chain, use the full cost for both,
even if their separate prerequisite
chains might include some of the
same spells.
