The next rows: Tiamat's Army (45 and 9), The Battle of High Hall Tower (41 and 9), The Lost Hollyphant (39 and 8), Elturel Has Fallen (37 and 9), and Into The Fire (35 and 7). The store screenshot of Tiamat breathing fire is Elturel's Last Stand, the same adventure. Trials of Mount Tiamat are a different activity with a one-week timer. Do not use this wave table as the trial's health bar.
Favored foes against fiends, from the table: Ezmerelda with a feat, Reya, Farideh with a specialization, Van Richten with a feat, and Wyll. That is the set I read. A patron order for fiends in Avernus starts at Elturel's Last Stand.
