Tartarus is the main dungeon in Persona 3 Portable that appears every night during the Dark Hour at Gekkoukan High school. Persona 3 Tartarus is the only place where you can find and defeat Shadows except for the full moon phase.
Tartarus resembles a huge tower that grows out of the ground with randomized floors except for a few main ones. We recommend doing Tartarus as soon as it becomes available every time. Try to reach the next barricade in one or two nights. It will not only give a level boost to your persona and party members, but also you will have ample time to increase your social links in your free time until the next full moon appears.
Sometimes people from Tatsumi port Island go into Tartarus unknowingly. Elizabeth will inform the party about the people and you can rescue them from particular blocks for some sweet rewards.
Persona 3 Tartarus blocks
It is divided into blocks, 6 to be precise. The blocks are further divided into floors which have sub-sections controlled by mini-bosses. There are 264 floors excluding an optional Block, Monad Depths, which has 10 additional floors.
The first floor is the main entrance while the 264th is the rooftop. Entry to every subsequent block is barricaded until you defeat Arcana Shadows (main bosses) on the full moon phase. So, Tartarus can’t be completed in one night as the Main bosses appear on specific dates throughout the year. Teleport points are available at the entrance and sub-sections.
