Thanks for the responses. I guess I'll temporarily use and level a few SR accessories for progression towards getting SSR accessories since I'm not confident my teams can handle the 4th quest as I lack many healer girls and don't want to rely on rng potion drops. Mabye even selling my N ans R accessories would be a better idea for getting the shop ones. Well regardless, not in a hurry unless there's going to be difficulty spikes in the near future.
