You've acquired a taste for flesh of your own kind. Whether or not this is a taboo depends on your culture and society, however this takes a toll on your sanity and physical health.
Consuming meat of a creature of the same type as you (typically Humanoids eating Humanoids) causes you to lose 1d6 points of Sanity, and against Illness effects you take a -4 to Bodily Defense.
The first time you trigger this trait to cause you to lose sanity, you earn an additional 1 TP. Every time you would acquire a Mental Disorder from consuming flesh, you earn an additional 5 TP instead of 1.
If you are immune to losing sanity, sanity damage, or Mental Disorders, you lose this trait and must choose a new one.
