I was told that using Ns to level up SRs and above are actually a waste of Ns. Just participate in the AWs fight to get Slimes. Max the Slime level then fuse it with both great success and 2x exp to the SR. Thats the most efficient way to getting a maxed lv SR. As the poster above said, summoning is also a possible choice.

Imo, if you have no slimes, I would rather keep tHem rather than trying to fuse it to the SR. Also, it is easy to max lv a SR against lv200 AWs. As long as you get the last hit.
