  This spell briefly disrupts the biology of a living being, inducing a brief state of system shock where the victim's muscles clench and she suffers a kind of seizure. Creatures with Constitution 12 or less are automatically affected, whereas those with Constitution scores of 13 or higher receive a Fortitude saving throw to negate the effect. The effect lasts for only 1d4 rounds, causing the victim to suffer a -6 circumstance penalty to all rolls.
