Reagent Magic

Reagent Magic is a form of indirect magic that can be performed by nonbloods, and is cast by combining certain materials and items to produce and channel the magic instead of a true sorcerer channeling it through themselves and other objects. While genuine magic can only be cast by a sorcerer or Arcane animal Reagent magic can be cast by anyone with the proper knowledge and materials. While most sorcerers seem to prefer reagent magic as a kind of back up or addition source of extra energy when they are either not powerful enough or to drained on their own to cast the desired magic, there are some who study and practice it regularly.
There are cases where Sorcerers who are more involved with non-Blood society and people will teach non-Bloods reagent magic to allow them to better interact with them and possess a form of magic themselves. While more complex and not as direct as regular magic, Reagent magic can potentially match or even rival all but the most powerful conventional magic spells. Ashley is mentioned to be teaching her Non-Blood girlfriend Holly reagent magics in their free time but has only been mentioned to have done basic spells like small object levitation. The magic fused with the technology behind Age of Adventure created by Russell Barnes is also Reagent based with him using very powerful Reagent magics to perfect his VR technology as well as the use vegetative body of Logan Reyes as a source of its magical effects. Some of Sylvana's Enlightened minions also use versions of Reagent magic to perform more powerful spells as what is given to them by her is limited compared to genuine magic. 
Material mentioned in the practice Reagent magics vary greatly including things like: Hippogriff tears, Argon powder etc.
