First of complete the game with a normal character. When youve done that start a new game on two player and have the character you want to have with high stats as player two with player one as the character you completed it with. It will work for both of the characters but better with a new one. Keep killing the boss intill you get your second character to about left 21 or 31 for 60 - 90 points.. If you have a lot of free time try and get them to level 41 or 51 120 - 150 points. Dont use any of the stats yet. When you have your desired level go to frogsville and use the character you want to make with good stats. When your on the level use the stats and let the character die from one of the Kobolds. Click retry and your character should have all the stats after you upgraded but all of the points to do it again. Keep doing this untill you have the desired stat line. Dont forget to save before doing this. On some the Kobolds might not hurt your character at all so if this happens load the game and go to the bonus mission where you have to collect the pearls and do the same with the points but let your air run out. And after some time of doing this you should have a character that can kill the legendary boss as if he was just another little guy. Enjoy.
