Elden Ring's Shadow of the Erdtree DLC has been shown off with an official reveal trailer, and this has come with more questions than answers in true FromSoftware fashion. A focus on the mysterious story of Miquella appears to be defining the upcoming expansion, something that fans had predicted for months leading up to this announcement. What wasn't likely anticipated by fans, however, is the introduction of Messmer the Impaler, a brand-new boss fight who acts as the mascot of Shadow of the Erdtree.
