AMYGDALA HYPER-ENHANCER

Although the amygdala hyper-enhancer seems to put the recipient on edge, this is a popular upgrade for casters.  A dark matter coil is implanted around the brain stem of the recipient.  This coil over stimulates the amygdala heightening its ability to detect fear and prepare for emergency events.  This augmentation provides the recipient with a +2 circumstance bonus to Perception checks to avoid surprise and to their EAC/KAC if they provoke attack(s) of opportunity by casting while threatened.  The advanced model of the amygdala hyper-enhancer increases the circumstance bonus to +4.  In addition to all the benefits of the advanced model, recipients of the superior amygdala hyper-enhancer can spend 1 Edge to act during the surprise round, or avoid provoking attacks of opportunity while casting.
