I'm 9-0 for fights my level... Level 8 guys challenging me and winning don't count

Here are some tips.
You can make as many accounts as you want.
You get 1 exp per unique ip for a pupil (Im not sure if this is per day)
When that pupil levels after the first 24 hours you will get 1 exp
You get one bonus per level
There are 3 confirmed pets, wolf, bear, dog, its rare to get one as there are only 3 vs many other bonuses including simple stat increases.
You get two exp per win and one per loss (only during daily arena battles)
6 arena battles when you register then 3 per 24 hours. If you win all 6 arena matches you can end the day at lvl 3.
Some of the better bonuses (listed in order of usefulness high-low)
Bear (Does about 20 raw damage independent of the brute)
Meat Club about 60 raw damage
Mourning Star about 35 damage
Trident (I saw you stab a guy in the heart with a trident)
Sword about 20 or so damage
Knife about 12 damage seems to multiple attack more than the other weapons
Mid range
Thief (can steal a weapon thus a lvl 1 with thief may lose against a guy with higher str, but can beat a guy with the lvl 1 club guy who was beating everyone else)
Shield (With weapon is pretty decent, early on without one it is meh)
Thick Skin (Essentially nullifies the dmg from high str characters)
Some of the weaker bonuses
Net (may be better later on when everyone has a pet)
Some ability that can scare a pet, don't remember the name atm (same as net)
Various abilities just increase stats, but higher than a stat increase from non ability
Any stat increase that does not come from a (special ability)
