So I've been trying to get niobe labs done sence black armory, I loved the DLC and still enjoy the content, however I've been hunting the ghost shell sence I've got the sparrow and ship. Apperantly you can get the shell from bergusia ignitions, so what exactly are the requirements for it. Is it incredibly rare on completion, do I need powerful weapons, or do I just need a legendary weapon, or is the olny way niobes torment (if that's the case then the collections tab is misleading)[armory][/armory]
