Reflexive Magic (occasionally referred as Automagic) is a variety of casting which, instead of relying on the conscious mind, uses the subconscious. The subconscious is the autonomous or self-independent part of the mind.
Similarly to Symbolic Magic, Reflexive magic does not require thought into casting at all; it is an extremely rare phenomena where spells and enigmatic attributes can be seen associated with a certain magi or person. How this happens has yet to be proven due to the intricacy of a sentient mind and how it functions along with a mana circuit.
An example of this is seen in rare characteristics magi where a person is afflicted with subconscious ability to manipulate an element they control. Not seeming to be wet after contact with water, apparent immunity to heat and flame, instantaneous healing of minor wounds, etcetera.
