I remember hearing his voice for the first time and being scared shitless because I thought he was right beside me.
And yeah, he was bad ass. Like twice as tall as his minions and that huge sword, one of the best Diablo moments of all time I agree.
GONNA CHOP YOU!
I will never forget the "Zhar the Mad" quest though... I think that was one of the first moments I briefly hated Diablo 1 because he ownd me so many times and frustrated the hell out of me.! I love challenges like this though. Back when boss's didn't crumple from runewords lol.
