This is an upward-extending branch consisting of 4 levels; it is reached by a second upstair in the Dungeons of Doom located on the level immediately below the Oracle level (and therefore between DL 6 and DL 10).
All levels in the branch are no-teleport and ineligible to leave bones files. Level teleport is also forbidden within the branch. Monster creation within this branch is biased towards neutral monsters.
On all Sokoban levels, diagonal movement between boulders or between boulders and walls, pushing boulders diagonally, or picking boulders up, are disallowed actions; all walls are undiggable and unphasable. Certain actions carry -1 Luck penalties:
Each level will be one of two variants, chosen with equal probability. Each level contains four random food items, one random ring, and one random wand (along with lots of boulders). The marked traps on each level are holes (with the exception of the bottom level, where they are pits), and are inescapable.

In addition to the usual items on the level, the points marked 'x' each contain a scroll of earth. The marked traps are pits.

One of the points marked 'x' (chosen randomly) contains a bag of holding (in the left variant of the level) or an amulet of reflection (in the right variant). In addition to the monsters in the marked zoo, there are two giant mimics imitating boulders randomly placed on the level.
