A Primer is a form of knowledge organization that is a introductory work on a specific subject (Lores) written in such a way as to allow the reader to learn/uptake, understand, and integrate the most basic informative elements of a subject reflecting a process or power. It is assumed that the reader has no relevant experience, and starts the presentation of its information at the absolute beginning required to understand a subject. This may consist of any manner of recorded (digital, physical, etc.) works of instruction (words, pictures, etc.) which facilitate understanding. The knowledge learned reflects Normal Impression memories, not Seared Impressions.
Mystic Scope: The instruction tells a story of a achieving understanding through a vision or Meditation to unlock their potential. This is one source of the Didactic Tradition.
Requirements to Use: If Tutelage is self-taught via a Primer, the learner/observer must be fluently literate in the language it is written in or means it is imparted in (taught by another directly). Actually gaining any benefits assumes the character has the basic requirements (knowledge/Lore, powers, scholarship/reason/intelligence/etc.) to make use of/wield such power.
SIGNIFICANT EXPERIENCE: Reference works and basic exposure alone may only provide the foundation for gaining a [mechanics based] advantage. To reflect the practice and experience to gain that benefit consistently, typically requires a cost in Character Points.
Often this is a documented account which details how a character can become proficient with minor magicks through a specific Tradition.
