GURPS - Compendium 1..

Solitary Magery 10 points for first level,
6 points/level for 2nd and 3rd levels
Your magical abilities are at -3 for every person (or other
intelligent being) within five yards of you, and -6 for anyone
touching you. It is believed that this actually represents a degree of
magical sensitivity so great that it is disturbed by the mana
"ripples" caused by living beings.
As partial compensation, a mage with this disadvantage gets a
roll vs. IQ to notice any time an int elligent creature enters or
leaves the 5-yard area around him - but this only works on a
single person. If there is already someone standing next to the
mage, he won't notice if someone else approaches.
Song Magery 10 points for first level,
6 points/level for 2nd and 3rd levels
A "song-mage" must be ungagged and able to sing in order to
cast his spells or detect magic (as per Musical Magery, above).
Characters with this type of aspected magery are not freed from
the ritual of speaking to cast spells due to high skill level (see
GURPS Magic, pp. 7-8).
Star-Aspected Magery 8 points for first
level, 5 points/level for
2nd and 3rd levels
A star-aspected mage (or "darkmage") can only use his powers
when the sun is not in the sky - on average from 6 p.m. to 6 a.m.
When the sun is up, the star-mage will have none of his magical
abilities, although a look at his aura will reveal he is a mage.
This type of mage is not affected by being in a building,
underground, and so on. Only the sun's position matters. He
will know automatically (if he is awake) when it is one minute to
sunup and one minute to sundown.
Sun-Aspected Magery 8 points for first
level, 5 points/level for
2nd and 3rd levels
A sun-aspected mage can use his powers only when the sun is
in the sky - on average from 6 a.m. to 6 p.m. During solar
eclipses, sun-mages have no powers! The effect of other astronomical
events (e.g, planets with two suns) is up to the GM.
When the sun is down, the sun-mage has none of his magical
abilities, although a look at his aura will still reveal that he is a
mage.
This type of mage is not affected by being in buildings,
underground, and so on. Only the sun's position matters. He
will know automatically (if he is awake) when it is one minute to
sunup and one minute to sundown!
Mana Damper
Variable
This is a specialized form of Magic Resistance.
For 5 points, you can effectively reduce the local mana level
by one step, but only for yourself and persons or things that
you're actually touching. For 5 points more, this effect extends to
everything in the same hex. Each additional 5 points extends the
radius of the effect by one hex. You can reduce local mana by
two steps by paying the base cost for your range again, and by
three steps by paying it yet again. You must also pay the base
cost again for the ability to turn the power on and off.
No individual with the Mana Damper power can ever have
Magical Aptitude or learn any spells.
Example: A character has Mana Damper in a 3-hex radius.
This costs 10 points for the first hex, and 10 more points for two
more hexes of range, for a total of 20 points. This is his base
cost. If he wishes to prevent all spell-casting within his radius on a
normal mana campaign world, he will need to pay the base cost
again to bring the local level down to "no mana," bringing the
total to 40 points. If he can turn this ability on and off at will, he
must pay the base cost again, for a total cost of 60 points.
Contrast this advantage with the Mana Enhancer advantage,
below.
Mana Enhancer
Variable
You are inherently magical, and actually radiate mana. In
some campaigns, this may force you to hide from unethical
mages!
For 25 points, you can increase the local mana level by one
step, but only for yourself and persons or things that you're
actually touching or carrying. For 25 points more, this effect
extends to everything in the same hex as you. Each additional
25 points extends the radius of the effect by one hex. You can
increase the local mana level by two steps by paying the base
cost for your range again, and so on. You must also pay the base
cost again for the ability to turn the power on and off.
If you have the Mana Enhancer advantage, you can never
have Magic Resistance; moreover, mages get an IQ + Magery
roll to notice you! This advantage does not confer any special
ability to cast spells; for that, purchase Magery. Of course, if
you can raise the local mana to "high" or better, then you can
cast spells even without Magery.
Example: A character has Mana Enhancer in a 2-hex radius.
This costs 25 + 25 = 50 points for the first hex, and 25 more points
for another hex of range, for a total of 75 points. This is his base
cost. To be able to turn this ability on and off at will, he would
have to pay the base cost again, for a total cost of 150 points.
Contrast this advantage with the Mana Damper ability,
above. Note that this advantage can be very easily abused, and
should be kept under strict control.
