Taking no damage

[Macon The Black]

i hit that glitch yesterday and was all by myself since the one i came with left. i was leveling the 3 raiders that reapear at the front then peopel came in and another friend came. well this one guy wouldnt leave the guys i was taking out alone, he said he hated cheaters adn didnt care that he was stealing my rep and guys. then said i could rott in hell for all he cares, i had my friend talking for me since he couldnt see my local chat. anyone know the tormenta one. i know how to get into the rock but not invisible/invincible one. i got bored with kingshead and cutthroat. anyone help me out?
