History of Inotam, Oblivion's Triune

Inotam, Oblivion's Triune is the final boss of the Sundial activity, added in Season of Dawn. Accounts differ on how it forms: one describes the three Psion Flayers merging into one, while another describes the Psions appearing briefly before Inotam replaces them. Each third of its health lost sends the fireteam to fight one Psion Flayer in a separate arena. On return, players must claim Sync Plates against incoming Cabal attackers, with one more plate each time; claiming all plates removes Inotam's shield. Defeating Inotam unlocks the Flayer Slayer and Inotam's Ruin triumphs, which help unlock the Dawn title.
