The floors themselves are also far more complex than the previous strata. B26F and B29F consist of extensive warp mazes. B27F is mostly dark and littered with holes that force the party to fall to a large area in B28F, which in turn consists of powerful damage tiles and is the earliest place where the player encounters Depth Dancers, the strongest FOE in the labyrinth. B30F is comparatively simple, but also houses the strongest enemies in the game.

- During Story Mode, the player is directly taken to B30F to kill the Yggdrasil Core. The shortcut leading directly to its room is unlocked, while the doors that lead to the large hallways in the sides of the room are locked. After seeing the credits, should one continue their current file instead of going to a New Game+, they will be able to explore Claret Hollows in its entirety, and the shortcut on B30F remains unlocked.
- The complete layout of B30F resembles the Yggdrasil Core itself.
