I gave up
I'm sorry. I did it after months and months saying no to KEM farming due to how messy it is... I did it. And couldn't be more glad about it. Even without the x5 EXP multiplier I managed to go from 130 to 142 in just 3 days. So if you are still considering it, just do it. You can design far from it, I guess, or be extremely creative. But it's worthy.
