Revision as of 19:05, 25 April 2013

Magic Theory, sometimes called Hermetic theory, refers to the set of universal magical principles developed by Bonisagus and the other Founders.[1] Magic theory is a body of knowledge that describes how magic works, and transcends the scope of any single Art.

There is an Arcane Ability called Magic Theory that represents knowledge of, and practical experience with, magic theory.[2]

Importance of Magic Theory

Magic theory is Bonisagus's second great invention, after Parma Magica.[1] It is a single, universal theory that describes how all magic works, meaning that magic from almost any tradition can be explained in terms of Hermetic theory. (Note that mysteries generally teach knowledge outside the conventional boundaries of magic theory.)[citation needed]

According to the the ArM5 rule book,

The most immediate advantage of Hermetic magic was that it allowed wizards of diverse magical backgrounds to share their knowledge. Before Bonisagus’ theory, the practice of magic had been highly individualized and therefore limited in scope. With the ability to share and accumulate knowledge, Hermetic magi gained an immense advantage over other wizards.[3]

Thus, magic theory makes it possible for magi of the Order of Hermes, even those of different Houses, to teach magic to one another and to write books about the Arts.

Characteristics of Magic Theory

While Bonisagus's theory is very useful for making magic understandable, that is not the same as making it entirely systematic or predictable. The ArM5 rule book points out that every magus's magic is a little bit idiosyncratic[4] and using magic is complex and not entirely predictable.[5]

The Ars Magica rules don't describe the actual tenets of magic theory in much detail. Magi know a lot about magic theory, but players only need to know how the magic rules work. Magic theory incorporates various forms of occult knowledge including astrology[5][6], alchemy[7], and the magical properties of gemstones[8].

The Limits of Magic describe what magic can't do.

The Laws of Magic are part of magic theory and the rules occasionally refer to them.

Arcane connections are important in magic theory, allowing a magus to affect a distant person, creature, or object through sympathetic magic.

The Magic Theory Ability

The Arcane Ability, Magic Theory[2], represents an Ars Magica character's proficiency in understanding and correctly applying magic theory. Magi use it extensively used in their laboratory activities, such as inventing spells and creating enchanted devices.

Learning Magic Theory

All magi need a certain minimum score[9] in Magic Theory to comply with ArM5 rules. It's advisable to create a magus character with a higher score than that bare minimum.[10]

Non-magi can learn the Magic Theory Ability (note that access to all [[Arcane Ability|Arcane Abilities at character creation is restricted), but it primarily useful only to characters who work in an Hermetic laboratory: magi, apprentices, and familiars. One of the few uses non-magi have for Magic Theory is in copying books: scribes who copy books on the Arts need a certain score in Magic Theory or else they will produce corrupted copies.[11]

Uses of the Magic Theory Ability

The Magic Theory Ability is very important to a magus because it affects practically all of a magus's laboratory activities. Specifically:

  • It is used to calculate the magus's Lab Total.[12] It also determines the bonus to Lab Total a magus can get using experimentation.[13]
  • At character generation, a magus's Magic Theory score partly determines the maximum Level of the forumulaic spells he can know.[14]
  • It determines the amount of raw vis a magus may use in a season of lab work.[15]
  • It determines how many different pieces a magus can combine into a single enchanted item to obtain different Shape and material bonusses.[16]
  • A magus needs a certain minimum score in Magic Theory to set up his own laboratory[17]
  • When creating an advanced magus character (one who has been out of apprenticeship for several years before starting play), the character's Magic Theory score determines how many enchanted items he may have[18]
  • A score in Magic Theory is required to serve a magus as a laboratory assistant.[19] The Gift is normally required as well[19], but failed apprentices[20] are an exception.
  • Magic Theory is used in certain Mysteries, such as Potent Magic[21] and Bind Curse.[22]


Alternatives to the Magic Theory Ability

Magi of House Merinita can use their score in Faerie Magic in lieu of Magic Theory under certain circumstances.[23]

The Mystery of Vulgar Alchemy uses Magic Lore in addition to Magic Theory.[24]


= History of Magic Theory

Bonisagus the Founder developed Hermetic Magic Theory, which assimilates and extends the knowledge of earlier magical traditions such as the Cults of Mercury, Mithras, and Osiris[25]. Bonisagus created it by carefully studying spells from several different magical traditions and identifying the commonalities among them. By extracting and formalizing these common principles, Bonisagus created a framework that made it easier to learn, teach, and record magical spells and enchantments.[26]

Presumably, the other Founders helped to develop magic theory, but ArM5 only discusses the other aspects of Hermetic magic, such as spontaneous magic or enchanted items, that they contributed to the early Order.[27]
