I agree about Maxing the HUR can take a lot of N cards. If you have time and enough Metal Slime, please feel free to test the amount of Exp the slimes provide. My guess is that you should start with a lvl26 or lvl27 Metal slime and see where that gets you. If you have an optimal solution, please feel free to share it. I'm sure others would want to know the absolute minimum required as well.
