Taking the more pessimistic view, I even doubt we’ll see a fight where Ruo is using all his gear and items. I mean, how many damn full HP recovery items must Ruo have? And rings that, I don’t know, boost stats by 5 or even 10 each? A robe with 99 per cent DR? Of course, like in all Xianxia, there’s a limit to how many buffs and defences you can stack onto a low-cultivation body (otherwise Ruo wouldn’t have simply lost to LC, even though he was much weaker at the time), but until then, who knows what Ruo has at his disposal. For this reason, I fear that against Ruo, the ‘maximum’ we’ll face will be him using transformations, arts, his swords and perhaps a ‘revive’ or two (if it even comes to that).
