I hate these linear arena games.
...because if you fuck up once, you have to restart the game. There's no way to fix a bad point allocation, no way to do side quests to get more points. If you hit a wall, you're just done.
That said, this is a very good arena game. Llama races are key to getting the best equipment, just save before you go to the races, bet all your money, and quit without saving if you lose, then reload. Oh well. Having tried and failed as a warrior, I recommend if you're going warrior, make sure you have enough int to get life drain by the time you're level 13, coz you gotta face the bad-ass chick at that point.
