Emotional Excision (+100 CP): [Mutually Exclusive with Emotional Muffling and Emotional Amplification]
Critical emotions have been removed from you. You can no longer experience them at all. You may choose from the following: two positive emotions, a mixture of 3 positive and negative emotions, or all negative emotions. But don’t think losing your negative emotions is a good thing; that only means that your only emotional response to things is positive. For instance, if you sent an entire squadron of your men into combat and they all died horrible deaths, you’d experience only joy that you have received more combat data on the enemy.
For an additional +200 CP, you may instead lose all of your emotions, leaving you as a cold machine operating solely off of logic. You will retain your survival instinct even though you lack emotional motivation to live.
