Ziggurat

A ziggurat is a strange tower constructed of twenty seven levels of incrementally larger combat arenas, each containing greater wealth and even greater danger than the last. Whatever entity created this monstrosity charges a steep price for entry. Beware, for a ziggurat is not a place for the faint of heart: even the bravest and most skilled adventurers have met their ends in one. While a portal to safety will be present on every level, once left, a ziggurat cannot be re-entered.

Ziggurats are the most dangerous, unpredictable and lucrative branches in the game. Each Ziggurat has 27 oval-shaped floors, with each floor growing in size as you go down, containing increasingly more monsters of higher difficulty. The entrance to each floor closes as soon you walk through it; the only way out is at the opposite end of the floor. There, you will find large amounts of treasure, including armour, jewellery, valuable potions (many of which are potions of experience), manuals, and many other wonderful things (except for gold), as well as one set of stairs going further down and two portals leading out of the Ziggurat.

Each floor of a Ziggurat contains a huge number of monsters of a particular theme. Most are sets of monsters that would be generated in a particular branch, but some are ad-hoc. The deeper you go, the more dangerous it becomes. Deeper floors will have a greater ratio of powerful monsters to weak ones, may generate all monsters awake and wandering (0% chance for Zig:1-4, 100% chance for Zig 25-27), and may block teleport control (0% chance for Zig:1-6, 100% chance for Zig:25-27).

Ziggurat portals may be found on any floor of the main Dungeon (rarely) or any Pandemonium floor (8% chance). A portal can also be summoned by the Trowel card of a legendary Deck of dungeons. Entry is denied until the player pays the admission fee, which is always between 2,100 and 14,000 (mean 4,668) gold. Summons cannot follow the player through a Zigguart portal or stairway.

Once one has left a Ziggurat, the portal turns into an empty arch and may not be reentered. Any new portal encountered or created leads to the first floor of a fresh Ziggurat. Ziggurat portals have no timers.

Monster Themes

Natural Monsters

• Monsters from the Slime Pits (objects are placed in a room with a door so they aren't eaten).
• Monsters from the Snake Pits (snakes of all kinds plus nagas).
• Monsters from the Shoals (merfolk).
• Monsters from the Lair.
• Monsters from the Orcish Mines, plus stone giants and moths of wrath, with depth-dependent priority for orc warlords, orc knights, orc sorcerers, and orc high priests.
• Monsters from the Elven Halls, with depth-dependent priority for deep elf sorcerers, deep elf blademasters, deep elf master archers, deep elf annihilators and deep elf demonologists.
• Monsters from the Vaults, plus ancient liches with depth-dependent priority.
• Draconians (starting at Zig:6) of all colors and walks of life.
• Monsters from the Spider's Nest with bonus ghost moths, red wasps and tarantellas.
• Monsters from the Dwarven Hall, with possible deep dwarf death knights and unborn deep dwarfs.
• Monsters from Lair:8's spriggan forest, with bonus spriggan defenders, spriggan air mages, spriggan druids, and spriggan berserkers.

Demons & Undead

• Monsters from the Crypt.
• Monsters from Cocytus.
• Monsters from Gehenna.
• Monsters from the Iron City of Dis.
• Monsters from Tartarus.
• Single Pandemonium lord (starting at Zig:8) and Pandemonium demons.
• Monsters from the Abyss.

Multiple Pandemonium Lords

• These floors contain either Pandemonium demons or lords (multiple ones, with no limit). Near Zig:27, you may even have 30 Pandemonium lords on a floor! Note that giant eyeballs may appear on this floor too, so be careful!

Mummies

• These floors contain mummies, with depth-dependent priority for greater mummies (on Zig:27, 1/8 are greater mummies and the rest are random, including greater mummies).

Angels & Daevas

• These floors are rare (20% of normal likelihood) and each monster is with equal probability an Angel or a Daeva. If you worship a good god, they should be mostly peaceful and there shouldn't be any problem.

Fighting Strategies

You should enter a Ziggurat as the last thing in the game if you are planning to finish it, as Zig:27 can potentially be the hardest place in the game. Preparation is somewhat similar to Pandemonium, but you need even more care since the enemies are much harder.

You will need the following:

• High experience level and skills.
• For spellcasters, the ability to cast Fire Storm and/or Ice Storm and/or Tornado at Great, ideally Excellent.
• Blink and Control Teleport or Controlled Blink at Excellent, to avoid getting surrounded, create some distances from powerful enemies, or just escape.
• A ring of sustain abilities and an amulet of stasis for absorbing death curses on mummy-themed floors.
• An amulet of resist corrosion for acid blobs on Slime Pit-themed floors.
• As many resistances as possible; at least something like rElec, rPois, rC+, and rF+. You should strive for rN+++, especially if you're susceptible to torment.

The following are recommended, though not essential depending on the character:

• An amulet of resist mutation for mutagenic glow, shining eyes and neqoxecs. If you're a caster, these tend to die before they can even peek at your genome.
• An amulet of conservation or cloak of preservation to avoid getting your scrolls and potions destroyed. This can also replace the amulet of resist corrosion.
• Scrolls of identify to identify loot, scrolls of remove curse to remove mummy curses and remove cursed loot, scrolls of fog to block enemy sight, and scrolls of blinking as a backup to Blink/Controlled Blink. Don't hoard too many as they might get burned and you will be finding some anyway.
• Wands of healing, hasting, and anything else you might need.
• Potions of curing to cure confusion (especially if you use a ball of energy), potions of heal wounds to recover lost HP, potions of porridge for instant nutrition, potions of might/agility/brilliance to enhance your battle prowess, and potions of magic to recover MP in a pinch.
• Royal jellies or potions of restore abilities to restore stats drained by mummies' curses.
• Some permafood depending on your metabolism and the spell hunger costs of your spells, but you will may some potions of porridge on some floors; those should keep you fed.

Keep in mind you're limited to 52 items; only bring what you know will be useful, else you might not be able to take all the loot you want with you. Artefacts with multiple resistances and intrinsics are your friend!

Conjurer Strategy

Sample Runs

• hyperbolic's uber Naga, who fully cleared several Ziggurats: [[1]]
• sh's Fire Storm run: [2] with ttyrec at [3]
• Luca's Extension + Ice Storm run: [4] with ttyrec at [5]
• See also trucutru's run with Nemelex Xobeh: he played a Naga Fire Storm conjurer with Fighting at 27 (and thus around 320 HP!) worshiping Nemelex Xobeh.

The basic strategy is to use Necromutation, along with all relevant buff spells, and alternate between casting a Storm/Tornado and channeling MP. Depending on your god choice, you can also use Sif Muna's channel (more reliable) or Vehumet's MP gain on killing (somewhat more random, but passive). Keep in mind that you can't escape to rest for MP, so make sure to have backup in the form of a crystal ball of energy, potions of magic, Sublimation of Blood, etc...

Note: don't bother using Shatter. This, at Earth Magic 25 or higher, does damage to everything in LOS, and while the damage is comparable to Ice/Fire Storm for non-flying/levitating monsters (3d55 at power 150 and more for skeletons and simulacra), it is only about a third for flying/levitating ones (such as a lot of Pandemonium lords). It would take an average of 8-9 hits to kill a flying Pan lord.

Specific Floors

On Pandemonium lord floors, be prepared to be on the receiving of the occasional Lehudib's Crystal Spear and Dispel Undead. If you use Fire Storm, try to position yourself so that non-lord monsters, Pan lord summons and your own summons create a buffer that prevent the lords from coming close to you. Then blast with Fire Storm without destroying your monster shield. If you use Ice Storm, try to get the direct path blocked by a non-lord monster, while still having an opening to shoot Ice Storm near the lords.

On mummy floors, wear an amulet of stasis and a ring of sustain abilities. Try not to kill too many greater/guardian mummies at once since you may get 3 points of random stat drain for each kill. If one of your stats dips low, try to swap in weapons or jewellery boosting it. If a stat gets dangerously low, semi-controlled blink to a corner, surround yourself with summons, end Necromutation, eat a royal jelly or quaff a potion of restore abilities, and recast Necromutation right away. Flooding the level with powerful summons to soak as many curses as possible can also work.

On angel/daeva floors, get out of lich form, cast Regeneration, and try to overpower them. If things go badly, consider casting Borgnjor's Revivification. If you decide to escape, go as near to the exit as possible, possibly using a lantern of shadows, cast Death's Door, and then alternate Storm/Tornado to scrolls of blinking/Controlled Blink and mana channeling to get to the downstairs as soon as possible. Once you are at the downstairs, apport any useful object until Death's Door runs out. Alternatively, you can escape the Ziggurat, but note that nearby angels/daevas will follow you out, so make sure you come out on a clear level and teleport away.

On dwarven floors, mages casting Fire Storm should be very wary of deep dwarf death knights and unborn deep dwarfs, both in and out of LOS. You will take severe self-inflicted damage if you flame even one of these while Yredelemnul's Mirror Damage ability is active. (The mirrored damage ignores both your resistances and AC, unless you've cast Death's Door.) If it's in your LOS, you'll have seen it "kneel in prayer and [be] bathed in unholy energy." Thereafter, for approximately 20 turns, its glyph's colors will be alternating. You can also see if Mirror Damage is active by examining it to see if it is "reflecting injuries".

On slime floors, the treasure will always be somewhat protected, in a centered chamber rather than on the open floor.

Equipment

In addition to the general equipment:

• Enhancers (e.g. rings of fire/ice, staff of conjuration/fire/cold/air, etc...) to enhance the power of Fire/Ice Storm and/or Tornado as needed. A robe of the Archmagi is amazing for this purpose.
• Staff/rings of wizardry to improve the success rates of Fire/Ice Storm and/or Tornado, if necessary. Also, try downgrading your shield type (large shield to a normal shield, normal shield to a buckler) if your Shields skill isn't very high to get rid of the spellcasting penalty. Your offense is your best defense.
• A crystal ball of energy if you have high Evocations (you will probably find one soon in the Ziggurat) or a staff of channeling.
• Identify scrolls, as many as you have. You're going to be going through a lot of stashes.

Optional Spells

You may want the following spells:

• Ring of Flames: to enhance Fire Storm's power and allow you to walk in clouds of flame.
• Airstrike: to kill giant eyeballs, which may appear in Pan lord floors, if you lack Fire Storm and its smite-targeting.
• Sublimation of Blood: you can use this on potions of blood (if you're a vampire), corpse chunks, or on yourself (especially if you are a high HP race). If your floor had monsters that left corpses, consider butchering a few of them and bringing the chunks to the next floor.
• See Invisible, Insulation, and Resist Poison if you don't have access to those resistances otherwise.
• Phase Shift to boost your EV.
• Dispel Undead: to kill undead anacondas rushing at you, skeletal dragons who survive Fire Storm, or to kill mummies one by one.
• Lehudib's Crystal Spear: to kill dangerous monsters (especially Pan lords) who get close to you.
• Tukima's Dance: to get rid of any cursed weapons you identify by wielding.

Crusader Strategy

See coolrobin's Ogre Chaos Knight of Lugonu: morgue and ttyrec

See 78291's torment immune Demonspawn crusader/reaver of Okawaru, failed run at [6], first ziggurat at [7], and second ziggurat (with death to daevas) at [8] and [9].

• First, convert to Lugonu (for corruption and self-banishment), The Shining One (for peaceful angel/daevas, divine warriors), Elyvilon (peaceful angel/daevas, healing), Okawaru (attack speed boost and skills boost), or possibly Nemelex Xobeh (see section below).
• Set up as many spells and enchantments as described for conjurers as you can. You probably won't have Necromutation (and can't use it anyway with the good gods) or Fire/Ice Storm and Tornado, though.
• The Silence spell, while counter-productive for pure conjurers, works beautifully for a crusader-type character against spellcasters. It even stops mummies from tormenting and smiting! Use a lantern of shadows along with it when needed.
• Bring a way to channel mana, and a staff of energy for hunger-less casting.
• Consider bringing a rod with Abjuration.

Fight in melee with all buffs (Haste, Might, etc...) except for berserk: it will definitely expire before you've cleared all monsters on the harder floors, and being slowed/exhausted in the middle of a pack of demons or some such is a surefire way to die. Angel/Daeva floors can be handled by proper god choice or by escaping.

Nemelex Xobeh Strategy

See trucutru's run with morgue [10] and ttyrec [11].

You can convert to Nemelex Xobeh and sacrifice all the stuff in the whole dungeon. This will allow you to receive gifts of decks and stack decks to be able to use specific cards at will.

• You will be finding many decks, and Nemelex will help you to use them effectively.
• You can use the Tomb card to create a safe haven and then a chokepoint in the Ziggurat. This is extremely powerful, since only a few monsters will be in sight. It is probably optimal to do so in such a way that the tomb is contiguous with walls. If you dig a corner against the wall, only that square will be visible. Doing so facing a Ziggurat corner may be advisable too.
• The Portal, Elixir and Damnation cards are also incredibly useful (the first does instant controlled teleport, the second full HP/MP restore, and the third banishes you to the Abyss if you are the only creature in sight).
• Decks of all types have powerful effects: see the Nemelex guide for more details.

Spell-less Strategy

Do not attempt to fully clear a Ziggurat without spells of some sort. It is very likely to be fatal. Having said that, the first few floors are usually safe for many XL27 characters, although this can still be risky.

Strategies For Troublesome Floors

Skip With Death's Door

See "Conjurer strategy" above. Cast Death's Door after getting as close as possible to the stairs. Make a break for it.

Banishment With Lugonu

Banish yourself to the Abyss. You'll have to give up on the rest of the floors, but it's the safest and most reliable mean of escape. In 0.10 or newer, you will return to the same level after leaving the Abyss.

Banishment With Distortion Weapon and Amulet of Stasis

You may also try to banish yourself with a distortion weapon. However, you have about the same chance of going to the Abyss as to be instantly teleported on the level, damaged and confused. An amulet of stasis or -TELE artifact will prevent this, though, and allows you to use distortion with the only downside of confusion and HP damage. Be prepared to cure numerous bad mutations - another effect of distortion unwields is to induce glow, and if you're in dire enough straits to be using distortion unwields to escape, you probably don't have time to let it dissipate safely. In 0.10 or newer, you will return to the same level after leaving the Abyss.

Throwing the Distraction

(The old standby.)

In version 0.10 or older, use Projected Noise at the bottom of the map, then walk around the top end (or vice-versa).

Wizard Mode

Ziggurats can be entered in wizard mode using &L to place a vault called "enter_the_ziggurat", &{ to map the level, XT to teleport to the portal and &o$ to acquire enough gold to enter. You may also just use &P to place a portal to a map called "ziggurat".
