Sacrifice

Jump to navigation Jump to search

In NetHack, sacrifice is an action performed at an altar that can reduce your prayer timeout and make prayer safe, increase your luck, and confer other effects that depend on the sacrifice. As an offering to the gods, this naturally breaks the atheist conduct.[1]

Description

A sacrifice generally requires a corpse that is fresh to be 'prepared' via the #offer extended command while standing on the altar. This involves touching the corpse, whether it is in your inventory or already on the altar: a cockatrice or chickatrice corpse will result in immediate stoning unless your character is wearing gloves.[2] The corpse in question must be aged no more than 50 turns since its creation or removal from an ice box (if it was created in there) to be accepted as a sacrifice and consumed, with the exception of acid blob corpses.[3] The only non-corpse item that can be offered is the Amulet of Yendor (and imitations thereof) - offering your character's god the real Amulet is required to win the game.

Whether or not the sacrifice is received well (if at all) depends on the value of the sacrifice, as well as the god whose altar it is offered on versus the one your character serves. As in many other instances, hallucination will change the resulting messages.

Ordinary sacrifice

Assuming a sacrifice to your character's own deity, a corpse with positive value will please them or reduce their anger, and a corpse may have a negative value if sacrificing it would anger them. The value of the sacrifice is determined in part by the difficulty of the former monster, and is usually equal to their difficulty + 1. If your character attempts to sacrifice a corpse with no value, usually a corpse that is too old as described above, nothing happens regardless of deity.[4] Partly eaten corpses have their value decreased by an amount roughly corresponding to the portion of the corpse that was eaten.[5][6] Undead corpses sacrificed by a non-chaotic character have +1 additional value.[7]

Sacrificing to your god

The effects of your god accepting a sacrifice of positive value on their altar are detailed in the table below, with the effects depending on their anger level, your character's alignment record and prayer timeout. Sacrificing the corpse of a unicorn, a former pet that died while tame or a monster belonging to your character's race has differing and often drastic adjustments to its value, including whether or not the sacrifice is to your god or another god – these are covered in the sections below this one. Sacrifices at cross-aligned altars are also covered in later sections.

The table also details if it is potentially safe to pray after a particular sacrifice; you can verify your prayer timeout and safety to pray by offering another valid sacrifice, or else through another method such as enlightenment. Remember that these actions only affect base luck, and that your luck can still be negative due to modifiers from cursed luck items.

Alignment Anger Prayer timeout Effect Message Safe to pray?
Any Greater than zero[8] Any If you are lawful or neutral and sacrifice a corpse from a monster of 7 difficulty or higher, or otherwise (as a chaotic) sacrifice a corpse from a monster of 11 difficulty or higher, your god's anger is decreased by a portion of the sacrifice's value, with a cap of 24 value:[9] 18 rounded down if you are lawful or neutral, and 112 rounded down if you are chaotic.[10]
  • If your god is pacified, your base luck is set to zero if negative.[11]
  • If your god's anger is reduced but they are not pacified, your base luck is increased by 1 if it is negative.[12]
  • Otherwise, if your sacrifice does not have enough value, a message is printed and nothing else happens.[13]
If your god is pacified and you are hallucinating: <Deity> seems cosmic (not a new fact).
And otherwise: <Deity> seems mollified.
If your god is less angry and you are hallucinating: <Deity> seems groovy.
And otherwise: <Deity> seems slightly mollified.
If their anger has not lowered and you are hallucinating: The gods seem tall.
And otherwise: You have a feeling of inadequacy.
  • Maybe
  • No
  • No
Negative None Variable Your alignment is increased by the lowest of the following values:[14]
  • 24 points.
  • The value required to bring your alignment record to zero.
  • The value of the sacrifice.
You feel partially absolved.[15]
  • Maybe (your alignment record may still be negative, and you may also have negative Luck or a prayer timeout)
0 or greater None Greater than 0[16] Your prayer timeout is decreased depending on the value of your sacrifice (represented by x), with the minimum for possible timeout being zero:[17]
  • If you are lawful or neutral, prayer timeout is decreased by 25x2, or 12.5 times the sacrifice's value.
  • Otherwise (if you are chaotic), your prayer timeout is decreased by 125x6, or ~20.8 times the sacrifice's value.
A message is printed, and you gain luck depending on whether or not your prayer timeout is now zero:
  1. If your prayer timeout is set to 0 after this, your base luck is set to 0 if it is negative.[18]
  2. If your prayer timeout is not set to 0 after this, your base luck is increased by 1 if it is negative.[19]
If your prayer timeout is zero and you are hallucinating:[20]
Overall, there is a smell of fried onions.
Otherwise: You have a feeling of reconciliation.

If your prayer timeout is not yet zero and you are hallucinating:[21]
You realize the gods are not like you and I.
Otherwise: You have a hopeful feeling.

  1. Yes (if overall luck is positive)
  2. No
Greater than 0 None Variable The following occurs:
  • If your base luck is 0 or greater and you are at least at experience level 3, you have a chance of receiving an artifact as a gift.[22]
  • Otherwise, your base luck is increased by 524 of the sacrifice value (rounded down), and if it is still negative, it will be set to 0.[23]
If you receive a sacrifice gift:
An object appears at your feet!
The voice of <deity> <thunders/booms/rings out>: "Use my gift wisely!"
If your luck is increased and you are blind:
You think something brushed your <feet>.
If this occurs while you are hallucinating and not blind:
You see crabgrass at your <feet>. A funny thing in a dungeon.
Otherwise:
You glimpse a four-leaf clover at your <feet>.
  • No
  • Yes (if overall luck is positive)

Sacrifice gifts

As mentioned above, if your prayer timeout is 0, you have positive alignment, you are at experience level 3, your base Luck is 0 or greater, and your god is not angry, you have a 110 + 2xy chance of an artifact gift being placed on the altar, where x is the total amount of existing aritfacts and y is the number of gifts granted previously.[24] Receiving a gift unrestricts the corresponding weapon skill if applicable, exercises wisdom, and also increases prayer timeout by rnz(300 + 50x) where x is the total amount of existing aritfacts.[25][26][22][24] Artifacts generated this way are erosion-proofed, non-cursed and set to at least +0 enchantment.[27]

A sacrifice gift consists of an artifact appropriate to your alignment: your first gift will always be a co-aligned artifact that does not hate your current form, if any are available.[28][29] If your role has a guaranteed first gift, its alignment is adjusted to your starting alignment at the beginning of that game;[30][31] your role's gift is favored over other co-aligned gifts, provided it has not yet been generated elsewhere and you are not currently under a different alignment. Unaligned artifacts become eligible for sacrifice gifts once a co-aligned artifact has already been gifted, or else if no eligible artifact can be given this way.[32]

Demonbane is the first sacrifice gift for Priests.

Sacrifices of negative value

There are also sacrifices that displease your god, whether in general or under certain circumstances; these have a negative value and similarly negative effects depending on the offense you committed in offering the corpse:[33][34]

  • Sacrifice of a co-aligned unicorn to your god or a cross-aligned unicorn that matches the alignment of the altar has a value of -5, and your character loses one point of wisdom while that altar's god smites them.[35] Sacrifices involving unicorn corpses are somewhat complicated and covered in full in the appropriate section.
  • Offering a monster of the same race as your character on a co-aligned altar is always a negative-value sacrifice if you are not chaotic or in the form of a major demon - see that section for details.
  • Sacrificing a pet to a co-aligned god at their altar after it died while tame has a value of -1, which will anger them.[36] The corpse will not be consumed in this case, and your character is given the aggravate monster intrinsic along with a -3 penalty to alignment record.[37] If the monster went feral (i.e. became untame) before dying, it no longer counts as a pet and may be killed and sacrificed as usual.

Cross-aligned altars

(Level + 2) / (Level + 8)

If you make a sacrifice of positive value at an altar that does not belong to your character's god, and it is not a high altar or an altar in Gehennom, this is treated as an attempt to convert it.[38][39] Trying to convert a compatible altar has a chance of success that rises with your experience level, with a probability of XL + 2XL + 8.[40] Failing will incur a -1 luck penalty and abuse wisdom, while succeeding will increase luck by 1, exercise wisdom and change the altar's alignment to that of your character.[41][42] Hostile minions may be sent by the god whose altar you tried to convert regardless of whether you succeed, with the chance dependent on your alignment record and experience level.[43][44] Any aligned priest tending to an altar that is converted will become hostile.[45]

If you make a sacrifice of negative value at an altar not of your alignment, a conversion attempt will not occur: the altar's god is angered and smites you, while your character's god will have their own anger decreased by one, and the corpse is not used up.[33][34]

If a conversion is attempted on an aligned altar, and you have either negative alignment record, an angry co-aligned god, or a sacrifice of a unicorn that is of your character's alignment (which is elaborated on below), there is a chance of your character having their alignment converted to that of the altar.[46][47] If this occurs, you also lose 3 luck, have your alignment record reset to zero and have your prayer timeout increased by 300, and this will always occur if done via co-aligned unicorn sacrifice (which has a value of -1).[48] Converting alignments by any means removes all points of intrinsic protection you have accrued. Attempting a converting sacrifice on an unaligned altar, or while already permanently converted by any means, will cause the sacrifice to be rejected and incur several penalties: the anger of your character's current god increases by 3, said god smites you unless you are in Gehennom, -5 penalties are applied to luck and alignment record, and your character loses 2 points of wisdom.[49] If your alignment is converted before you have been admitted to your quest, the game becomes unwinnable.

Sacrificing on a high altar not belonging to your character's god will bring the full wrath of that altar's god upon them:[50][51][52] a bolt of lightning, followed by a wide-angle disintegration beam if the character survives the lightning.[53][54] If this occurs on the Astral Plane or in Moloch's Sanctum (where the high altars are ordinarily encountered), the angered deity will then send in three sets of hostile minions.[55]

Same-race sacrifice

If a corpse that you sacrifice belongs to a monster of the same starting race as your character regardless of its age, then several effects will occur, with some depending on your alignment:[56]

  • A chaotic character sacrificing a monster of their race sacrifice on any altar of their own alignment will gain +5 alignment and +2 luck, while a chaotic character doing this on an unaligned altar incurs a -2 luck penalty but still gains +5 alignment.[57][58] A chaotic character performing same-race sacrifice on any normal cross-aligned altar will instantly convert the altar to chaotic, angering any attendant priest.[59]
  • A character that is lawful or neutral performing same-race sacrifice on a non-chaotic altar converts the altar to chaotic, angering any attendant priest, and takes several penalties: a -5 penalty to alignment and luck, loss of a point of wisdom, abuse of wisdom unless they are in the polyform of a demon, +3 to their god's anger, and being smited by that god unless they are in Gehennom.[60][61][62] A lawful or neutral character performing same-race sacrifice on a chaotic altar will destroy it instead and anger any attendant priest, with the same penalties otherwise.[63]
  • As with regular sacrifice, attempting same-race sacrifice on a high altar that is not chaotic while your character is not chaotic will immediately raise the anger of that altar's god to maximum and prompt them to smite the character.[52][51]

Regardless of alignment, if the altar is chaotic or unaligned, a major demon is summoned: this will be either Yeenoghu or Juiblex if either of them have not been generated, or a random major demon otherwise[64][65] - 89 of non-unique demons summoned this way will be foocubi, and can otherwise be any major demon.[66] The summoned demon will be peaceful if you are chaotic and hostile otherwise.[67] Summoning a demon this way always paralyzes your character for three turns, ignoring free action.[68]

Sacrificing unicorns

Sacrificing unicorn corpses has varying effects dependent on several factors, including the altar's alignment, your character's alignment and the unicorn's alignment.[69] A unicorn's alignment is represented by its color - white is lawful, grey is neutral and black is chaotic. These are the critical points to remember:

  • Sacrificing a unicorn of your alignment will always anger your character's god and cause them to smite the character, regardless of the outcome. If done on a cross-aligned altar, you will also be converted to that altar's alignment, while doing so on an unaligned altar causes additional penalties without changing your alignment.[49] Doing so on any high altar will maximize the anger of that altar's god without any conversion attempts.[52]
  • As mentioned above, sacrificing a unicorn on an altar matching its own alignment will anger that altar's god into smiting the character, and the character loses one point of wisdom.[35][33] If the altar and unicorn are not of your own alignment, your god's anger is instead reduced by one.[34]
  • Sacrificing a unicorn whose alignment does not match that of the altar's god or your character is treated as a regular sacrifice with bonus effects.
    • Sacrificing a unicorn of a different alignment at your god's altar always grants a +5 bonus to alignment record, along with printing a message depending on your current alignment record; it does not reduce your god's anger beyond the normal value for that sacrifice.
    • Sacrificing a cross-aligned unicorn at a cross-aligned altar that does not match its alignment attempts to convert the altar as normal, with a +3 bonus to value.

The effects are summarized in the following table:

Sacrificing the Amulet of Yendor

The goal of the game is for the player character to retrieve the Amulet of Yendor from the Sanctum of Moloch and offer it at their god's high altar on the Astral Plane, so there are naturally mechanics that help complicate this goal – be sure not to offer them a cheap plastic imitation by accident!

Attempting to offer the Amulet of Yendor on an unaligned normal altar in Gehennom will anger Moloch into smiting you, while doing so on any normal altar elsewhere will print a specific message that hints at your goal. Doing so with an unknown cheap plastic imitation has the same effects, and will print an additional message hinting that the offered Amulet was fake. Offering an unknown fake on a high altar incurs a -1 luck penalty and identifies the fake, while offering a known fake on any type of altar has -3 value and will incur a -3 luck penalty, a -1 alignment penalty, and increase the anger of that altar's god by 3.

Offering the real Amulet of Yendor on any high altar will immediately end the game in one of three ways:

  • If the character offers the Amulet at the high altar of their god, they will ascend to demigod-hood.[70] This does not take any conversions into account, only checking to see that the character's alignment matches that of the high altar, so it is possible to ascend a character as their original alignment after permanent conversion by using a helm of opposite alignment. This applies a score multiplier of 2× if the character never converted from their starting alignment, or 1.5× if they converted and used the helm to change back.
  • If the character offers the Amulet on a cross-aligned high altar, that altar's god gains dominion over their god and allows the character to escape in celestial disgrace.[71]
  • If the character offers the Amulet on the high altar to Moloch in his Sanctum, Moloch retains dominion over their god and kills the character, and a character revived by life saving is then reduced to dust.[72] The only way to survive this is in explore mode or wizard mode, by declining when prompted if you want to die, though the game ends regardless since the character is then forced out of the dungeon.[73]

History

Altars and sacrifice are introduced in NetHack 3.0.0. From this version to NetHack 3.4.3, including variants based on those versions, if no artifacts are eligible for a character's first sacrifice gift, they will not receive any artifacts for the entire game unless they change alignment. This most commonly occurs with elven Priests or Rangers who name Sting and Orcrist in the hope of guaranteeing Stormbringer as their first gift, only to fail because Stormbringer had been generated in bones already. In these versions, changing alignment also gives an alignment bonus or penalty based on the character's starting alignment, rather than uniformly resetting their alignment record to zero.

In NetHack 3.6.0, commit 2adc83e1 introduces the lack of score multiplier if ascending while of a different alignment, as well as the lower score multiplier for a character ascending while converted back to their original alignment via helm of opposite alignment.

Messages

Variants

SLASH'EM

In SLASH'EM, sacrifice can also net a character other boons from their deity, including having wielded and worn items blessed or even being given tame minions. SLASH'EM also adds several new artifacts, including many that can be given as sacrifice gifts – several roles are given a guaranteed first gift, and some roles with a first gift are given guaranteed second gifts.

The Eye of the Beholder and The Hand of Vecna are artifacts that can be sacrificed at an altar, and both are treated as maximum-value corpses for this purpose, though doing so is generally a Bad Idea unless the player truly does not want the artifact in question - the Eye of the Beholder is generally considered the least useful of the alignment quest artifacts, and may be the more acceptable of the artifacts to sacrifice in order to pacify an angry god, particularly for chaotic characters.

Below is a table describing artifacts that can be gifted and their eligibility as first or second gifts.

GruntHack

In GruntHack, characters can receive mundane items as sacrifice gifts, which are likely to have an object property and significant enchantment. The handling for mundane gifts is found in artifact.c: the weapon or armor generated and its accompanying object property is selected from a list of appropriate types, and leans towards particular weapons based on the character's race and role (e.g. a gift of a two-handed sword will always become a tsurugi for Samurai); non-artifact weapons that are gifted will always be of a weapon skill that the character can train in.

SporkHack

In SporkHack, characters can receive mundane items as sacrifice gifts, which are intended to be "junk" according to a comment in the code within pray.c. The odds of an artifact being considered as a gift over mundane items increase with the character's experience level:

Experience level Odds of artifact
1-3 0
4-8 110
9-11 15
12-13 310
14-16 25
17-18 12
19-20 35
21-22 710
23 45
24-25 910
26+ guaranteed

Despite their designation as junk items (as most players will be used to receiving artifacts), the mundane weapons and armor given as gifts will always be erosion-proofed and have an enchantment from +3 to +5, and non-artifact weapons that are gifted will always be of a weapon skill that the character can train in.

FIQHack

In FIQHack, a mechanism called piety determines when a character receives gifts or becomes crowned from altar sacrifice. In addition, only gifted artifacts affect the rate of future artifact gifts, ignoring artifacts obtained via wishing.
