Saving my reincarnated world with the help of my ultimate MMO character

On behalf of an angel called Eternity, I got reincarnated to help rescue her world and was given 3 wishes and a class of my own choosing.

I chose my class and the 3 wishes to help me on my journey in this world.

My 1st wish is not to be limited by my class to master any other skills and powers or in any way possible (Unchained skill).

My 2nd wish is that I can master skills as fast as I can (A Great Understanding skill).

My last wish is for my MMO character to be alive in this world as she is the ultimate character that I spent time and money on.
