There is a bit more dialogue to pry from Cain Darkmoore.
When you say "what bunker battle blade" he answers;
" The bunker battle blade was crafted and enchanted for use by warriors only. It has the power to strike down those creatures which hide behind their magic. Once bestowed upon a warrior, it cannot leave your side or it shall vanish from this realm forever. One must perform the [green and blue] to earn such a blade."
He pretty much explains that this is a magical weapon, and that's probably all there is to this weapon, since the dps of the weapon is pretty bad. It has been suggested that there should be more to this sucky no-drop weapon, but after hearing Cain say this, I think not. Btw, I got the bunker battle blade from Capt Linarius with the Guard Bracelet hand in so that still works. I guess I will put the weapon up on the wall. ;)
