Blood Lust from the Ancients

"In ancient times there were Ancient Demons. They had tails, arms as big as a man's waist, and could toss humans like so much confetti. It was told that they had a bloodlust that could never be slated. Be glad they no longer live."

-Legend of the Ancients- Discovered during an excavation of an Upper Yard city.

Description
A powerful, mythical ability rumored to affect individuals under great stress. They would ignore all wounds and seek to destroy their enemies at the cost of their life, should they receive a mortal wound in this state. Soldiers who have seen this describe towering warriors who ignored all their weapons and threw them about like leaves to the wind.

Supposedly, the Badger Lord Utan have inherited this one hundred fold, and yet retain a little sanity.
