My Vanquisher was obtained via Crucible Package. I was so excited when I got it, it was my second Legendary Weapon (Right after Judgement VI). After that, I just knew I had to support New Monarchy. I didn't get the best rolls, but they were helpful nonetheless. I got the perks where you would get a faster reload after a Precision kill, and then the faster reload if your mag is empty. To say the least, I was a slaughtering Auto-Machine who never ran out of bullets! XD
