Ahoy!
So, lemme just say that the obsidian set is quite possibly my favorite set in the entire game. It looks so unique and honestly very pretty. However, I do have one major issue. It's not completable. If I recall correctly, in order to get the blunderbuss, you had to buy the external hard drive for sea of thieves. The banjo was sold along side some limited time hoodie. The rest can be earned through Twitch events.
Currently, I'm only missing the Blunderbuss, Fishing Rod and Banjo. As a completionist, it's hard to use the set without having the entire thing. This bothers me and I'm sure it bothers other people who don't have to spend $35+ just for an in game cosmetic. Hopefully, the banjo becomes a twitch drop like everything else. I also hope the Blunderbuss comes back in some way. Is there any news of these coming again?
