Wall

The most prominent features of the dungeon, walls block movement and often line of sight. In general, destroying or bypassing them requires one of a few specific abilities.

Wall Varieties

Rock

Template:Crawlquote Very common walls made from unworked stone which block LOS, but relatively easy to remove. Rock is the only material for which the Passwall spell functions, allowing you to slip through it. Destroyed by:

• Formicids' digging ability
• Dig (or a wand of digging)
• Shatter
• Fedhas' Overgrowth
• Lugonu's Corruption
• Dissolution

Translucent Rock

Template:Crawlquote Identical to rock walls, except they don't block sight.

For the purposes of attacking and other abilities, translucent walls are treated as solid walls. You can't attack or blink through these walls, even with piercing or smite-targeted attacks.

Stone

Template:Crawlquote More durable than rock walls, these require stronger magic to remove. Destroyed by:

• Shatter
• Overgrowth
• Corruption

Translucent Stone

Template:Crawlquote The stone analog to transparent rock.

Metal

Template:Crawlquote Metal walls are similar to stone walls. The metal prevents Shock and Lightning Bolt from bouncing off it. Lee's Rapid Deconstruction is stronger when used on a metal wall. Destroyed by:

• Shatter
• Overgrowth
• Corruption

Crystal

Template:Crawlquote Crystal walls are also similar to stone walls. They will reflect fire and cold, the same way stone walls reflect Shock. Lee's Rapid Deconstruction is stronger when used on a crystal wall. Destroyed by:

• Shatter
• Overgrowth
• Corruption

Trees

Despite having the ability to walk through plants, followers of Fedhas Madash cannot pass through trees. If lit ablaze, they cause forest fires that spread fire to the spaces (and other trees) around them. Unlike walls, they cannot be affected by Lee's Rapid Deconstruction or Frozen Ramparts. Destroyed by:

• Player-castable fire spells:
  • Inner Flame explosions (including from scroll of immolation)
  • Flame Wave
  • Fireball
  • Starburst
  • Ignition
  • Fire Storm
• Monster-only fire spells:
  • Bolt of Magma
  • Bolt of Fire
  • Lightning Bolt
• Nearby spreading flames
• Polar Vortex
• The Lernaean hydra
• Shatter
• Overgrow
• Corruption

If you are worshipping Fedhas, none of your spells are able to destroy trees (Fedhas actively protects them). Overgrow still works, however. Trees created by Summon Forest cannot be destroyed as easily; only Shatter / Overgrow / Corruption work.

Demonic Trees

Burning a demonic tree produces a cloud of seething chaos instead of fire.

Petrified Trees

File:Tree petrified1.pngFile:Tree petrified2.pngFile:Tree petrified3.png Template:Crawlquote

Unlike other trees, petrified trees can be dug through.

Mangroves

File:Mangrove1.pngFile:Mangrove2.pngFile:Mangrove3.png Template:Crawlquote These function identically to trees, save that they grow in shallow water.

Slime Covered Rock

Template:Crawlquote Found only in the Slime Pits, these inflict corrosion to any adventurer adjacent to one. Every slime wall currently adjacent to you inflicts 1 stack of corrosion (-4 damage and AC). Otherwise the same as rock wall.

Followers of Jiyva are immune to the effects of slime walls, and at 3* piety, can temporarily turn walls into slime. Jiyva-created walls deal acid damage to every enemy adjacent to them.

Destroyed by:

• Formicid's digging ability
• Dig
• Shatter
• Overgrowth
• Corruption
• Dissolution

Rune-Carved Stone

Template:Crawlquote These walls make up the outside portions of the central chamber of the bottom of the Slime Pits. They are otherwise identical to stone walls. Destroyed by:

• Shatter
• Overgrowth
• Corruption

Rune-Carved Clear Stone

Template:Crawlquote These transparent walls make up the interior of the central chamber of Slime:5. If the Royal Jelly is dead (or if you have high piety with Jiyva), these walls will vanish, allowing easy access to the Slimy Rune of Zot. Without these methods, these walls can only be destroyed with:

• Shatter
• Overgrowth
• Corruption

Iron Grate

Template:Crawlquote These block movement and line of fire, but they do not block LOS or line of effect, so smite-targeted attacks can get through. They are usually found in special vaults, often sealing away monsters with smite-targeted attacks. Destroyed by:

• Formicid's digging ability
• Dig
• Shatter
• Overgrowth
• Corruption
• Dissolution

You can use Blink, Passage of Golubria, or dispersal traps to pass in or out of grates. You can also use Dispersal or Disjunction to bring enemies out of grates.

Large Window

Template:Crawlquote Large windows are found in certain Sewers maps, and function identically to transparent rock walls.

Unnaturally Hard Wall

Template:Crawlquote Walls which are described as unnaturally hard are completely indestructible. The only way past them is to go around.

Translucent Unnaturally Hard Wall

Template:Crawlquote The indestructible variant of translucent rock.

Map boundaries

The following "walls" are found on the edges of certain floors.

Open Sea

Template:Crawlquote While not walls in the traditional sense, these impassable tiles mark the outer borders of the Shoals and certain Sewers layouts.

Endless Lava

Template:Crawlquote The fiery equivalent of the open sea tiles, these mark the outer borders of a floor across lava pools.

Endless Salt

Template:Crawlquote Much like open sea and endless lava, these mark the outer borders of the Desolation of Salt.

Dimension's Edge

Template:Crawlquote Yet another impenetrable level border, this time bordering the Roulette of Golubria.

History

• In 0.32, new decorative walls were added.
• Prior to 0.30, slime-covered walls would damage players and monsters with acid damage.
• In 0.27, demonic and petrified trees were added. Initially, burned demonic trees released durably summoned demons in addition to chaos clouds, but this was removed before the release.
• Prior to 0.22, Lee's Rapid Deconstruction could destroy walls, doors, iron grates and statues.
• Prior to 0.20, wands of disintegration could destroy rock walls and some other obstacles in the dungeon (doors, iron grates, trees, orcish idols, and most kinds of statues). Also, eyes of devastation could disintegrate rock walls with their Energy Bolt spell.
• Prior to 0.17, you could find boring beetles, arthropods capable of digging rock walls.
• Prior to 0.11, you could find walls of solid wax:

Wax walls were frequently found in killer bee vaults, though they could also appear near altars to Xom or in the Abyss. They often hid treasure, in particular royal jelly and honeycombs.
