We know Julian is powerful, we just don’t know how powerful Morden himself is.
Right now, it’s my personal belief that- just by how curses function, Morden would mop the floor with the protagonist if the two fought seriously right now.
Curses turn you into pure magic, and Mordens is an ancient magic- meaning a magic closer to the source of all magics and thus by its nature incredibly powerful. On top of that, even absorbing a minor, crappy curse makes you a force to be reckoned with. One of the things that makes curse users so scary is they don’t need magic circles to utilize a spell, being as they are made of magic they simply ‘manifest’ it.
Anyway onto what you are asking about, curse users are immune to physical attacks. Being pure magic, pure ‘energy’, you cannot deal physical damage to something like that. This is why the lore does indeed state that all classes, even Warrior or Berserker, can utilize magic, as otherwise when we get later into the story only mages would have been able to canonically fight curse users.
If they did fight before going to the Nimbus Sea Morden would definitely canonically defeat the protagonist. Julian one-shot us at basically the same state we are in rn (bc we didn’t train during that 1 month in prison and we immediately fought Calvus meaning we basically didn’t get any better in terms of combat) and we know Morden escaped that fight with Julian alive meaning it was either a draw or Morden killed Julian making him stronger than us.
I think even we can cast spells without magic circles, bc during the “Golden Age” of magic ppl used magic without magic circles but the drawback was that it took energy from the soul or smth and that’s why ppl started using magic circles, meaning we should be able to cast spells without magic circles right?
He said people we can’t fight we fight prince Revon after king calvus he is just really easy besides that I 100% agree I think Prince Revon is gonna pull a uno reverse card on us and beat us silly
My ass being imbued with magic anyways since everything we do is literally imbued with tiny bits and pieces of magic allowing us to fly around like fucking Mach 10 planes
