So this is the general stat stuff that I will, probably, go with

1 point in strength is equal to being able to lift one pound

1 stamina is equal to being able to run at full speed for a second.

each rank is 10x stronger than the last in the order of F, E, D, C, B, A, S, SS, SSS

Skills are gained once you gain enough proficiency in a task.

Just because two skills have the same name, doesn't necessarily mean they do the same thing.

Just so everyone knows, I won't be updating regularly, as I'm only doing this for fun. I would appreciate feedback in order to help make the story better
