Soul ranks and colours (skills have similar rankings and so do the beasts or monsters.);

F- black

E- grey

D- white

C- silver

B- gold

A- platinum

S- ruby

Ascendent- emerald

Deity- colourless

(All ranks from F to S are broken down into -, normal, +. And the beasts that are within the book shall be categorised similarly)

Classes;

Beginner> novice> intermediate> advanced> master

By the way this will also be important

1 intelligence stat is equivalent to 10 mana points

1 vitality stat is equivalent to 10 health points

Well this is what there is for now and I will increase on this information as the story goes on.
