I've used it a couple of times, helped 2 times out of 8.
First one was the funniest one, as I was scavenging and my invetory was full, while trying to not lose some guy (was the launch day if I remember correctly) I tried to search for voodoo in my inventory. He was *luckily* running in circles closing doors behind him, so I was able to sniff that stuff and boost my ms... Then he just panicked (I guess) and shot me, guess what, he critted me 6 times in a row, all of them were knockdowns and a knockout
, more than half of them were bypasses. Well, was fun at least.
(Other 5 fails were due to the fact, that "target" had friends
).
