Is it just me or is it almost impossible to become evil after reaching that!? I wiped out all of Ashbury, stole all the gold and items (took a great many trips) and my alignment dropped almost 10 points, what the hell do I have to do to drop below 50?... Next stop is Tarant!
Your savior is one of the 3 Gypsies! Your savior is one of the 3 Gypsies! one can be founded in Shrouded Hills another one can be founded in Tarant (all the way to the dock) They have magical weapons and potions and other stuff including helmets! So go to one of 'em and ask to barter. When you're lucky they have the helmet right away,otherwise 1.scroll away from the gypsy and yourself as far as you can(do not move yourself to scroll away from the gypsy) 2.advance time one day 3.go back and barter another time. Normally, she should now have other items to barter.Look if there's a "Dark Helmet" on her barter-inventory.If not repeat steps 1,2 and 3 until you finda Dark Helmet.Then, when you have it, eguip it and uneguip it for ...3 times.Go to your character editor and you'll see that your allignment dropped 60 points !For more evil allignment eguip and uneguip it even more! I hope this worked for you!
OR, you could just go get the Bangellian Scourge. One swing and hit with that takes your alignment to -100 instantly.
