These rules owe something to the Natural Magicians in Hedge Magic and
parts of Kabbalah. Parts of it do not totally agree with what is
stated in The Tempest.
Mercurian Rituals were usually performed in groups, and duplicate the
effects of Wizards Communion to some extent. Mercurian magi generally
require two skills when casting spells; Ritual Magic, a new skill used
when performing their magic; and Leadership used to determine how many
magi can be involved in the ritual.
Mercurian traditions did not divide magic into separate Arts but
rather thought of it as part of Natural Science. Thus Mercurian magi
also require Philosophiae, for designing spell effects.
Designing Spells
Mercurian magi may design any spell that a Hermetic magus can with the
following alterations:
- The duration of the spell may not be either Momentary or Concentration.
- Using the Circle and Boundary Target classes, Mercurian magi can affect
large groups, or even armies within clearly defined boundaries. Usually
this will require one participant of the ritual at each cardinal point.
[Option: participants at these cardinal points also require a
text during casting.]
- General level spells may only be designed by a magus with Ritual Magic
5+, and are designed as if the spell is Level 15.
[Note: Mercurian magi can decide the level of this spell at the time of
casting.]
- [Possible option: The spell cannot have more than Reach range.]
When designing a spell the designer may have a number of helpers equal
to his Leadership score. The designer totals his Int + Ritual Magic +
Philosophiae + Philosophiae of each helper, to get a lab total. This
lab total is treated in the same manner as a Hermetic magus' lab total
when inventing spells.
Casting Spells
Mercurian magi cast all spells as if they were rituals when
calculating for time of casting and fatigue loss, but use vis in the
same manner as Hermetic magi. A text of the spell to be cast is
always required, by the lead magus, during the ritual. If the magi use apt
paraphenalia they may add a Form and Effect bonus to the casting total.
Mercurian magi usually cast spells in groups of one lead magus and
several helpers. A lead magus may have a number of helpers equal to
Prs + Ritual Magic. Each helper must roll stress + Sta + Ritual
Magic 6+ to be included in the ritual. For each helper that botches,
three must succeed or the ritual fails, although the magi take the time and
fatigue penalties normally required to cast the spell.
The lead magus rolls stress + Sta + Ritual Magic + The Ritual Magic of
each helper + Aura + Any Form and Effect bonus. The result is the
spell-casting total.
As mentioned above, if a General level spell is being cast, the lead
magus may decide what level to cast it at. The lead magus requires a
Ritual Magic of 5+ to cast this type of spell.
