R5 ghost at only level 51? That’s beast man, congrats!
She is amazing. My first r5 too. I had her on r4 the day i explored act 5 (elder's bane) and took her straight to r5 and awakened without waiting another second and in the same day i also became Cavalier with her help. She is amazing and have no regrets ranking her and using my generic. Congrats and i hope she will help you as much as she helped me (and still helps )) ). Enjoy!
