Hey everyone!
We're sorry about the confusion from our last message. If you have earned the Onyx Four Pack MixPot for watching the “Sea of Thieves: Mixer Invitational – Battle for LA” stream on Mixer during E3 2019, then you must discover this content in the game. Your 4 new items are waiting for you in the Equipment Chest. You should see an Onyx Bucket, Onyx Compass, Onyx Tankard, and Onyx Shovel.
