Mechdragons' Massive Fortress is a technical dungeon that becomes available after completing Hill of Iris's Rainbow. It replaces the retired biweekly Mechdragon dungeon series.
This dungeon is a great place to farm +eggs on 1.5x drop Mondays, especially if there is a +egg bonus event going on. Unlike the other Technical Dungeons that may drop Evolution & Enhance Materials which can never have a +, this dungeon has the potential to drop a +egg on every floor.
