I've been playing through NWN again and was browsing the equipment database and found an item listed in the wrong category.
The Mantle of Epic Spell Reistance is listed in the Cloak section but is actually an Armour (Clothing type). I can't link to the Mantle image itself, but here's a quick link to the [url="http://www.gamebanshee.com/neverwinternights/equipment/cloaks.php"]NWN Cloak section[/url].
