Sounds like a skill issue. Joking aside I play largely old school games as a baseline, but maybe try playing some newer CRPGs to ease into it like Pillars of Eternity, Tyranny, or really any of Owlcats games. Also it could be worse ya couldve tried playing Arcanum which is rough even for me to play.
Are we sure this isnt a fae type situation with Sauron? Like its said you can only kill a fae with pure or true iron but I have found that they are rather susceptible to being hit by a 2001 Honda Civic.
