Unfortunately, whatever you have is it. If you don't already have the Shield of Mythics, there isn't any way to obtain it. [spoiler][quote][b]Achronos: The Heroic/Legendary/Mythic status was based off of the trust rating you had when we migrated bungie.net to bungie.next. Trust rating was the underlying "score" used to determine your title. halo.bungie.net is not necessarily displaying the title you had on that transition date for a variety of reasons. The point to remember is that when we migrated you to bungie.next, we copied your records to a new database, and froze them as your "legacy profile" at whatever they were at that moment in time. It is important to remember, though - if you don't have it when you start playing the game, then there isn't anything to be done. We did our best to try and match up your data with your current profile, but it has been nearly two years. There are very few people who have Mythic, though - it will be one of the rarer emblems in the game that the general population could have.[/b][/quote][/spoiler]
