Having checked your account via the app, [b]Legend of Acrius[/b] is not listed as having been unlocked to your Collections, meaning the item you are displaying in the video is the [i]temporary[/i] version that was to be used to complete the [b]Imperial Invitation[/b] Quest which awarded the [b]full[/b] version of the weapon. As the Leviathan Raid is no longer available, this Quest cannot be completed and the full weapon cannot be obtained in this manner. You can now get the full [b]Legend of Acrius[/b] by purchasing it from the [b]Monument to Lost Light[/b] using [b]Spoils of Conquest[/b] which are obtained by completing encounters and opening hidden chests within Raids.
