the questions they ask determine how fast you level up...
choosing the first answer for each question will make you level up quickly up to level 40, but makes it slower after that and takes about 1 million experience points to reach level 100...
choosing the middle answer to each question will make it average to level up throughout all levels and needs about 800,000 to 900,000 experience to reach level 100...
and choosing the last answer to each of the questions will make it hard to level up to 40, but very easy afterwards and only needs about 700,000 to 800,000 experience to reach level 100...
choosing the last answer is the best choice, and if you went over enthusiastic and trained till you were level 15 before going to traverse town, you will find it very easy to level up...
also choosing the weapons at the start determine when you learn certain abilities...
its probably best to choose the shield and sacrifice the sword the first time around, unless you are good at dodging, then do the reverse...
