Mental Damage

When a character takes Psyche damage, they are in danger of a variety of delitirious effects. The amount of Psyche lost will lead to certain effects based on how much of the total Psyche is damaged.
Ten Percent: Any time ten percent of your total Psyche is lost, your character loses one Permanent point of Psyche.
Half: When half of a character's Psyche is lost, they begin to exhibit Insanity Effects. The GM can choose one at random, but if he picks one that works with the situation, all the better.
All: When the character's Psyche is reduced to zero, that character will be rendered catatonic for 1d10 days, and when they wake up, they will have a permanent Insanity Effect or Mental Illness chosen by the GM.
Scared to Death: If the character's Psyche is reduced to ten percent of their total Psyche less than 0 (-7 for a Psyche of 70, for example), that character dies of fright.
