Hippiemancy is one of the eight major classes of magic in Erfworld. It is the major class defined by the Life and Matter elements together. According to Duncan Scone, Hippiemancy (among other things) concerned with relationships: "detecting and altering the forces of opposition and attraction which bind people or units."book-2-–-text-updates-011 Hippiemancy can be used to "quiet" a conflict and prevent units from engaging in combat. This happened to Wanda Firebaugh during her participation in an attack on Kiloton shortly after popping. Hippiemancer Olive Branch prevented Goodminton forces from engaging with Haffaton's by playing music to cast. The result was that Kiloton's forces could not swing their weapons with any force and merely tapped their opponents instead of injuring them.Peace (Through Superior Firepower) - Episode 012 Inner Peace (Through Superior Firepower) - Episode 012
The performance of Hippiemancy can affect the participants' perception of time, a phenomenon known as "flaking."
A practitioner of Hippiemancy is called a Hippiemancer.
Hippiemancy is the magic of relationships: detecting and altering the forces of opposition and attraction which bind people or units. With their confluence of Life and Matter and their absence of Motion Classes, it may be that within Hippiemancy Flower Power (Erf) might influence the environment/nature (space), Signamancy (Fate) might influence perspective/insight (vision), and Date-a-mancy (Numbers) might influence synchronicity (time in meaningful events, or put another way, the inverse of meaningful events in time).
Janis is a Grand Abbie of Hippiemancy. She has claimed that Parson Gotti is also a Hippiemancer; however, that statement may have been a ploy to defuse the situation when Parson arrived in the Magic Kingdom via portal (something that should be impossible for a non-caster), though she said it as she was dismissing Parson's suggestion that he was a Mathamancer or a Luckamancer.
