I was on the forums reading about this weapon when someone commented this.....
Drops - currently only in raid - from: boss 1/2/3, loot container(need key. key have chance to drop from boss4) - overall drop chance: <5% per raid completion (may not accrute)
With that being said can anyone confirm if this is true?
NVM it is confirmed on a post from reddit poster Lamertron he said this (PSA. New exotic can drop from EVERY boss in the raid. We got one (just one out of 8) from killing Boomer yesterday). He also took screen shots of the weapon. So thats good to hear, even if i dont manage to get the weapon i technically have 4 chances at it through out the whole raid.
