Experience: Characters level during the course of the game. Characters gain experience from battles, but also for participating in key story events. As characters level, they become more powerful, adding to their base stats and their attack abilities and options. As they level, they are also able to pilot more powerful mecha as well as to better pilot all mecha they can already pilot. At leveling, characters get a stat gain.

Additionally, the character has extra points to put where he or she pleases, it should be noted that some stats require more than one point to alter. Agility requires 2 points to be increased by one. Each point given to HP increases it by 5, and each point given to SP increases it by 2. NNTH goes up 1 point for ever 2 points of Dex or ever 1 point of Agility. Ever 5 points of Agility also increase the NNTH of any mecha that character pilots by 1. As the character reaches more advanced levels, they gain more extra points per level. Spirit requires 10 points to raise 1, and can only start being raised from level 10 on.

The different types of humans also have different raits of growth, that is, experience per level. This isn't noticible until after the first set of levels, however. This table lists the TOTAL experience of the character to atain the given level, not the amount needed in ADDITION to what you already have (so you only need 3,000 more to go from level 2 to level 3, not 5,000. The 5,000 will be the total experience your character will have [2,000+3,000=5,000])

Level 1: 0, you start at Level 1
2: 2,000
3: 5,000
4: 9,000
5: 14,000
6: 20,000
7: 27,000
8: 34,000
9: 41,500
10: 50,000
