The battle j*nkie trait or battle-crazed was a very nice trait to have. The longer the battle lasts, the more damage received, and how more excitement you had in the fight, determine the stat increase. It was like a boost of adrenaline but with a much greater effect.
There was another similar trait, which was the berserker. That trait also gave an incredible increase in stats; it was actually much better than the battle j*nkie trait if you talk about the increase in stats, but that one had a massive demerit, and that was the madness trait.
The longer the berserker trait is used, the stronger the stat increase, but at the same time, the greater the madness. The people with the berserker trait usually start attacking everything that moves.
They would only stop once they got tired or died, both of which were difficult to achieve, which was why, despite the weaker stat increase, the battle j*nkie trait was so much better than berserker.
