  And I'll agree that "undocumented" was a bit strong.  Let's just say that in the little bit of testing I did before beginning the game, I had no reason to notice that little icon - and do wish that something about it was said in the description.  To be utterly fair, even if I'd noticed it, I probably would have employed the weapon in the same way, and suffered the same catastrophic consequences of my usual bad luck.
