Is there any consistent way of beating SotC and above roadblocks without Myongest?

This is more so about Xiao and later roadblocks,seeing as how I'd like to try them without resorting to a strategy that just feels like completely trivializes the game. Since I'm not using nogrind (because the grind is somewhat fun,honestly) I'd at least want to clear them properly first and then go back with Yesod/ Gebura Myongest shenanigans.
