If you have a decent thief for a character, neither Mindflayers NOR Umber Hulks are smart or perceptive enough to notice an invisible/creeping thief. I did the entire Mindflayer area in the Underdark and the Sewars with an Assassin, a ring of invisibility, some potions of invisibility and a Cloak of Non-Detection. I just hit, ran, hid, hit, ran, hid.. you get the drill..I'd just run away and hide behind a corner and kill the next flayer/hulk, and rinse and repeat..
