At NF we have a stat system. This will determine your wolf's speed, strength, and stamina, and which they are best at, and which they are not so good at. When starting off, you have 20 stat points (except for pups, who will start off with 10.) you may use these on any of the fields. You may buy more stat points in the shop, though each field will max out at 50, you cannot go above 50 stat points for each category.
ex:
Strength: 10
Speed: 5
Stamina: 5
Total stat points: 20
