I get in a same group as my main, and log on and off, opening boxes etc with my main, then just log onto the 60 and open them up
Takes around 5 mins to get in a group, and you need a pal to invite you on both charas, but after that the farming is way easier. Instead of killing things with your 60, which takes time, you can kill them quite fast on your main.
