Hmm... So just rely on luck to find it, or is there a certain location for it? I got an arm piece that slows down time when my health gets below 20%. Saved my ass more than once. Got it from some legendary asshole ghoul that I died to 4 or 5 times before I gave up on guns and used a stack of about 5 frag mines. To atomize the lil b[i]i[/i]tch. I taunted the screen for like a minute when I killed him. >_> not my proudest moment.
