Just like most other MMORPG's, LEO has a level system. And fortunately enough, it's quite simple. Your rank is directly tied to your level, and your stat points are directly tied to your rank.
Beginner Rank: Levels 1-10. 6 Stat Points per level.
Rookie Rank: Levels 11-25. 9 Stat Points per level.
Intermediate: Levels 26-50. 13 Stat Points per level.
Veteran: Levels 51-?. 20 Stat Points per level.
You start the game with 10 stat points that you MUST distribute. However, upon leveling up from there on out, you do not have to spend your stat points and can save them. However, you can only save up to 15 stat points this way, and any left over stat points will be discarded.
