its just a basic idea i thought would be cool...i havent really thought much on it lol
revised:
50% chance:the master scofs at you "saying don't waste my time you worthless maggot"! you get the non buff embarrasement for 10 rds and lose a forest fight
40% chance:He pulls a kunai and lunges at you (his stats would be higher he is the "master")
You defeat him:he falls to the ground breathing heavily "I haven't had a battle this good in a while!" he offers his services for free and you gain 1 chakra point
He defeats you:you fall to the ground your vision dimming you hear the master laughing and the last thing you see is that stupid little boy from earlier
10% chance:he says "you could only benefit of my teachings! ill offer them to you for 2000 gold and 3 gems!"
Mmm, what if you lose against him you have a 40% of gain one chakra point "after you defeat your own master you feel more powerful. +1chakra and X Gem(s)
60% you reallize he have nothing to teach you.
if you lose 50% "Oops (something funny here) you are DEAD
30% "Arghh you are a noob, get out here!!" you run really fast and ten-ten was walking by there and laughs really loud at you*
you lose some charm and the negative buff- Shame 20 rounds.
20% "mmm, you have some potential, but nothing is free sooo...." X gold X gem(s)
Well, hehe =]..
