A bit more attention to capitalization and punctuation would be appreciated. And you could probably find the answer if you checked the 4.3 thread.
Also, your profile is broken. Please fix it.
regarding the 4.3 legendary in the first id:
would it theoritcally be possible to clear the first three DS bosses with a twinkraid, then join the raid with your main (to pickpocket the quest item), finish the solo quests and then start collecting the shadowy gems in mainraid the other day?
this way you'd be able to collect shadowy gems from 8 instead of 5 bosses
