[Fallout 3] Why do Point Lookout Tribals do extra unresistible damage?
gpt
There are two theories.  The first theory is that it's the punga fruit.  Long-term consumption of punga, starting from birth, has basically altered the physiology of the tribals and the swampfolk, and given them superhuman strength and damage.  Consequently, they can tear through power armor like it's tissue paper.  

And before you ask, no, you eating punga fruit won't give you similar powers.  You're too old to receive the empowering effects of the fruit.  It has to be eaten starting from birth.  

The second theory is that the island is affected by an eldritch abomination known as Ug-Qualtoth.  An aspect of Ug-Qualtoth's dark power was imbued into a book called the Krivbeknih, which was possessed by the Blackhall family for generations on the island of Point Lookout.  Centuries of influence by the Krivbeknih has given the island's inhabitants a degree of supernatural powers, including superhuman strength and endurance.
