I just got it from the second bottle quest and I'm playing as a Mechromancer. It's got better stats than my current shield (explosive spike), but I don't know what the special effect does (since the shotgun I found in the first one depletes my shield I'm assuming this has a catch too)?
Having to explain your joke doesn't make it clever, but having to have a joke explained to you doesn't make it unfunny.
Isn't that the one that "adds explosive damage to melee attacks"? I swear when I used it with Sharing is Caring, DT was only doing 8 explosive damage per melee attack...unless it adds more to your own melee attacks, I wouldn't use it.
I was using it on my Salvador with the Rapier you get from the third quest (200% melee damage) and I was doing pretty awesome. No idea what the downside is though, or for the Rapier for that matter (curse of the porcelain fists).
