Since Silvers are the only ones with magic, I don't want to see humans applying with powers. Here are the levels:

1 - Can perform small magic, like fixing broken glass or making pictures in the air.

2 - A stronger level of magic; can cast small spells.

3 - Even stronger; the user can use stronger spells and leviatate themselves and other things to a degree.

4 - Very strong; can cast high level spells and perform all levels of sorcery.

5 - The very strongest. The users of this level will be limited. Anything at all can be done with this level.
