I think they'd benefit taking a note from the witcher but not as linear.

For instance spirit/ghost creatures have them be susceptible to salt, silver, iron, holy water and a specific wood like holly. None are required to kill it, some have advantages over others or affect certain spirits more.

Maybe then I could be sneaky and have rare wood arrows with silver tips and eliminate from afar, I could be full rogue and sneak attack with blessed iron daggers, or just a big man with a plain sword and brute force my way through.

I think if you slapped Hatsune Miku on a dark souls screen and have her dancing going "jump!, roll!, duck!" People would realize it's not as much of a skill game as they thought.
