well if u have 2nd rb friend u can ask him/her to lucky time you and you go get hit by pheasants (without boots unless u want to upg boots quality) when ur dura drops by 1 just ask him/her to bless and go repair. It may succeed in about 100 tries i think cause i have spent over 50 times upgrading with lucky time (1 time ref 2 soc club went uni 2 soc now trying to elite it)
