Overview
Adventure Guide says
Dimensius attempts to Devour players almost immediately, and again every time he reaches 100 energy. His Growing Hunger increases with each cast, pushing the players' Collective Gravity to its limits. When Dimensius' health is depleted, he pulls players into the Dark Heart where they must quickly fly with Xal'atath to safety. He releases his conquered rivals to halt players' advance and attempts to obliterate them with Extinction and Gamma Burst. After a devastating counter-attack from the players and Xal'atath, Dimensius begins to Extinguish the Stars. Upon reaching 100 energy he again attempts to Devour everything around him, pulling his Accretion Disk ever closer.
