well the only way i did it is by getting 3 love forever rings and 3 regualar rings, then put 1 love forever in F-1, and 1 regular ring in a diff. F2. Then i used conquer clicky to push F1 about every 4 secs, and F2 about every 4 secs. When I used 2 love forever rings somethimes it would accidently push F1 twice before it pushed F2 and if that happens the Love forever ring won't be in F1 anymore.. So that is why I use 3 of them.
I'd be intrested in an easier way to lvl it though.
