gah ;P
First off, it really really needs a saving thing. Second, not really sure what happened, I ended up randomly losing after i just really pwning on one the bad guys. It says "Angry Zac Pascall defeats gladiator" but i can see in the background it says "gladiator defeats Angry Zac Pascall"
but this was my strategy, i put my points like this: 4,1,5,1,3,2,1. After the first match i put into 1 into stamina, one into vitality, and the other into strength. After that for the most part i put into strength.
As for battles i would taunt a lot doing damage until they got close enough to me, and dished out the rest. Like against angry zac, i did a fair amount of damage to him with the taunts and killed him in one hit before he got to me. I also avoided getting any weapon before the first three guys because after the 3rd guy they get you a pretty nice sword for free. I did buy a bunch of armor though.
The random thing was nice, I found that the random guys were usually a lot cooler looking that anything I could come up with.
