Who is the longest living curse/magic user

[razaral]

Can weapon and fighting style users get as strong as curse and magic users?

he didn’t have the grand fire curses, he created them after olympus fell it wasn’t arthur soloing every single god lol, there was entire war on mount olympus and some of the gods were on the humans’ side, arthur was just the leader of the opposition not sure if the war of the gods is mentioned on the lore doc or not but yea, its not a plot hole
