Do not toy with the fundamental force of life, for it is also the fundamental force of death.Spell Blowback is a natural occurrence in which the bodies normal fluctuations of Cortex either rapidly shift between positive and negative majorities, known as Frequential Blowback, or shifts massively from a positive to negative balance, or vice versa, usually through the incorrect use Core Magic. Frequential Blowback normally causes sickness, dizziness and other internal issues. True Spell Blowback can cause internal hemorrhaging, loss of limb, loss of life, evisceration, or atomization.
When a Cortex Sensitive or Core Magic user is exposed to either rapid fluctuations of Cortex or a massive inflation or deflation of Cortex, the body can react violently, as Cortex is infused through all cells of living creatures on Earth.
Areas with high Pure Iron concentrations can cause the effects of Spell Blowback to increase in magnitude and number of affected persons. This has been most notoriously recorded with the Oklah Military Recruitment Explosion in 1995.
