Discussion is about how strong the mc is compared to everyone else. He's stronger than the skeletons, there was nothing they could do against him other than. I personally don't even consider to be a "fight" since it's just the mc going against multiple waves of nameless, faceless, enemies. I mean the discussion before was about how the mc needed to get stronger so he doesn't struggle in a fight and he unless he unlocks and infinite stamina at some point he's still going to get tired when fighting to many people no matter how strong he gets. Just like how earlier I said that Taron is a threat mostly because of his influence and the fact he goes after others and isn't directly stronger than the mc. The skeletons arent directly stronger than the mc either.
As for Diana, not really. She stabbed him in the vitals and he got knocked down, managed to get back up later because of the cyrstals and he should have died, twice. He lost 2 out of 3 rounds and only managed to tie on the final round.
