Some new images have surfaced from people on Athena, who will apparently be #648 (unevolved) and #649 (evolved). Images have also surfaced of a supposed new monster from the Athen dungeon (see below).
There will only be a ‘super-hell’ class on this dungeon, and it will take place in a new stage the ‘Colosseum’. Full official details are here.
On the Niconico Max Murai show yesterday/last night, Yamamoto Producer announced Athena Descended is coming July 29th. There will likely be another Max Murai challenge on Niconico with this and possibly free stones if another no continue clear from Max Murai.
