Liked Elden ring or Dark Souls, then these may scratch that sophisticated and challenging combat itch. Although note, some are slightly easier than Souls games (yes, looking at you Witcher 3 and God of War...).
I have included Blasphemous and the Salt series, as although 2D they are still demanding with the combat.
Finally, there are some in this list I have not played or completed (Salt series, Dragon Dogma, Titan Souls, Let it Die, Lords of the Fallen), they are recommendations from others.
