Apparently, if one is to defend successfully against a challenging brute, no xp is given at all. Guess I have to pick my fights more carefully now.
I also got extremely humiliated by g-money.

I also lost my first tournament fight. Sadly, my brute is actually really a brute - strong, but slow and stupid.
