Editing Creating Magical Effects (section)

==Acting in Concert==

Multiple mages can work together to form an Effect that they'd have difficulty performing alone. Everyone involved must have at least Apprentice-level knowledge of the Spheres used (Rank 1), and they must find a way to make their paradigms and foci work in concert. A Ehtuanatos's knife probably can't enhance a Virtual Adept's computer program, for instance, but a Verbana's blood work could complement a Dreamspeaker's said paintings.

Each participant who has the Spheres necessary for the Effect can either choose to add one Trait to the main casting group's Aerete Trait total for purposes of the challengee, or he may add one grade of success to the spell if he also manages to make a successful test for the Effect.

Each participant who has at least rudimentary Sphere knowledge for the Effect, but not the level necessary to cast it, adds one Trait to the main caster's Arete Test. 

Each group of five un-Awakened acolytes who helps (generally by holding candles, chanting, forming circles, etc.) adds one Trait to the main caster's Arete Test.

Add all the modifiers to the Arete Test before any caster involved makes the challenge. Therefore, if 10 acolytes help and two mages work together on an Effect for which they have the right Spheres, both mages get to test. The acolytes add two Traits to both challenges, and if the assisting mage wins his test, he adds a grade of success if the main caster also wins.
