Hermetic Arts
Hermetic Arts is the common term to refer to the powers employed by Hermetic magi.
The 15 Hermetic Arts are subdivided into 10 Forms and 5 Techniques. The Techniques (and their abbreviations) are Creo (Cr), Intellego (In), Muto (Mu), Perdo (Pe), and Rego (Re). The Forms (and their abbreviations) are Animal (An), Aquam (Aq), Auram (Au), Corpus (Co), Herbam (He), Ignem (Ig), Imaginem (Im), Mentem (Me), Terram (Te), and Vim (Vi).
To manifest a magical effect the combination of at least one Technique and one Form is required. The notation of Technique-Form-combinations is usually expressed using the respective Arts' abbreviations, and concatenating the two abbreviations in camel case. This results in four-letter specifications. Requisites, if applicable, are appended in parentheses. For example, CrAu refers to an Creo-Auram-effect, while MuCo(An) would describe a Muto-Corpus-effect with an Animal requisite.
