Phasing is the ability to walk through solid tiles, such as walls and boulders. The property is possessed by xorns, earth elementals, ghosts, and shades.[1] This does not allow one to cross pools of water, or walk through those rare areas that are designated as non-phasing: all of Sokoban, a dividing wall in Moloch's Sanctum,[2] the inner wall around the Wizard's Tower, and the entire Astral Plane. In Sokoban, phasing players (but not monsters) are prevented from moving through boulders on a level until the puzzle is solved.

The only ways to gain phasing are to polymorph into a xorn or earth elemental, or to pray while stuck in a wall. Being stuck in a wall is considered a major trouble, and a successful prayer will normally teleport you to a safe position, but it will grant phasing for 4d4+4 turns instead if the teleportation fails.

Strategy

The use of polymorphing into a phasing monster to gain a combat advantage is dubious, as neither the xorn nor the earth elemental is particularly tough. Xorns cannot wear body armor or cloaks (these will be destroyed upon transforming), and earth elementals cannot wear anything.

Phasing may be used as an alternative to digging, especially for accessing items embedded in walls, or retreating if you're getting surrounded. It can also be used situationally to approach a shop from across an unmapped level and steal from it.

Strategically, phasing can be used to quickly bypass some areas of some maps. It is one way a Rogue can solve their final quest puzzle. Some players will polymorph into a phasing creature for Gehennom mapping to make the search pattern simpler; walking on the walls helps avoid traps.

Speed runners strive to phase into the correct turret of the Castle, and from there to the gem chamber (for Luck) and the trapdoor to the Valley of the Dead. The Valley, Asmodeus' Lair, and Vlad's Tower can be noticeably abbreviated with phasing. However, phasing is not a universal solution to non-teleport mazes, because xorns are slow and the lack of a cloak makes it dangerous to fight level draining monsters, shades, or Yeenoghu.
