This example allow the client to create a character from one of 3 races (Men, Elfs, Dwarves).
In addition you can give it one class or many (Archer, Wizard, Warrior) no matter the order of applience.
For Example:

ICharacter a = new Warrior(new Archer(new Men()));
ICharacter b = new Archer(new Warrior(new Men()));

a and b have the same functionallity, power & race.

Another Example:

ICharacter character = new Wizard(new Warrior(new Archer(new Elf())));

Now this one above has the greatest power among Elfs because he is wrapped with all of the concrete decorators.
