Sacrifice is a means whereby you can reduce your prayer timeout, increase your luck, and gain powerful [[artifact weapon]]s. Alternatively, you can also change your alignment by sacrificing to another god when you have negative luck. To sacrifice, you stand on an [[altar]], use the '''#offer''' command, and select a fresh [[corpse]] from your inventory or one that is lying on the altar. Unsurprisingly, this breaks the atheist [[conduct]]. The greater the monster's [[difficulty]], the more your god will appreciate it.

Creatures have a particular sacrifice value depending generally on their toughness. In some special cases, the value may be negative if the offering displeases your god; see below. Partially-eaten corpses normally have their value decreased by roughly the percentage that's been eaten. But NetHack rounds down, often to zero. For lawful or neutral characters, [[undead]] have an extra point of value,{{refsrc|pray.c|1232}} but this is only relevant to [[wraith]]s, since other undead corpses are automatically aged too much to sacrifice them.

Religion in NetHack

Sacrifice is a means whereby you can reduce your prayer timeout, increase your luck, and gain powerful artifact weapons. Alternatively, you can also change your alignment by sacrificing to another god when you have negative luck. To sacrifice, you stand on an altar,[1] use the #offer command, and select a fresh corpse from your inventory or one that is lying on the altar. Unsurprisingly, this breaks the atheist conduct. The greater the monster's difficulty, the more your god will appreciate it.

If the corpse is a cockatrice and your hands are bare, you suffer the effects of touching it, even if it wasn't in your inventory.[2]

Further effects depend on the details of the sacrifice.

Ordinary sacrifice

This applies to sacrifices made on your own god's altar that are not of your own race, not a pet, not a unicorn, and not made in the endgame.

If the creature is not an acid blob and is more than 50 turns old or more than 50 turns out of an icebox, it is rejected: "Nothing happens."[3][4] (Acid blobs never expire for sacrifices, although they will eventually rot away.) Otherwise, the sacrifice is accepted and you get "Your sacrifice is consumed in a burst of flame" if neutral or chaotic, and "Your sacrifice is consumed in a flash of light" if lawful.[5] If you are lawful and blind, you will instead get the message "Your sacrifice disappears".[6] If you are hallucinating you get one of the following messages: "Your sacrifice sprouts wings and a propeller and roars away!",[7] "Your sacrifice puffs up, swelling bigger and bigger, and pops!",[8] or "Your sacrifice collapses into a cloud of dancing particles and fades away!"[9]

Creatures have a particular sacrifice value depending generally on their toughness. In some special cases, the value may be negative if the offering displeases your god; see below. Partly eaten corpses normally have their value decreased by roughly the percentage that's been eaten.[10][11] For lawful or neutral characters, undead have an extra point of value,[12] but this is only relevant to wraiths, since other undead corpses are automatically aged too much to sacrifice them.

If your god is angry at you:[13]
Their anger is decreased by 1/8 the value of the sacrifice, or if you're chaotic by 1/12 the value of the sacrifice (chaotic gods are harder to appease).[14][15] The decrease in anger is always rounded down. High-difficulty monsters can be hard to find early in the game, but a black pudding from a sink will work.
If this reduces your god's anger to zero,[16][17][18] you'll receive the message that your god "seems mollified" (if hallucinating, "seems cosmic (not a new fact)"),[19] and your base Luck will be increased to zero if negative.[20]
If anger is reduced but not to zero,[17] your god "seems slightly mollified" ("seems groovy" if hallucinating),[21] and your base Luck will be increased by one point if negative.[22]
If anger has not been reduced at all, "You have a feeling of inadequacy" (if hallucinating, "The gods seem tall").[23]
If your god is not angry at you, but your alignment is negative:[24]
Your alignment is increased by the value of the sacrifice,[25] up to a maximum of 0 alignment[26] or 24 points,[27][15] and "You feel partially absolved."[28]
If your god is not angry and your alignment is positive but your prayer timeout is greater than zero:[29]
Your prayer timeout is decreased by 12.5 times the sacrifice's value if you are lawful or neutral, or 125/6 (about 20.8) times its value if you're chaotic, to a minimum of zero.[30]
If this decreases your prayer timeout to 0,[31][32] then "You have a feeling of reconciliation"[33] (if hallucinating, "Overall, there is a smell of fried onions"[34]) and your base Luck is increased to zero if negative.[35]
If your prayer timeout is not yet zero,[32] "You have a hopeful feeling"[36] (if hallucinating, "You realize the gods are not like you and I"[37]), your base Luck is increased by one if negative,[38] and it is not yet safe to pray.
If none of the above cases applied (i.e. your prayer timeout is zero, your god is not angry and your alignment record is positive):[39]
If your base Luck is nonnegative and you are at least at experience level 3, you may receive a gift.[40]
If you did not receive a gift (or were not eligible for one at all),[41] your base Luck will be increased by about a fifth of the sacrifice value (specifically, 10/48), rounded down.[42][43][15] If your base Luck is still negative after this, it will be set to 0.[44] If your Luck was changed by this, you will see the message "You glimpse a four-leaf clover at your <feet>."[45] ("You think something brushed your <feet>." if blind;[46] "You see crabgrass at your <feet>. A funny thing in a dungeon." if hallucinating and not blind[47]).

None of the possible effects will guarantee that you can safely pray; this is because they only affect base Luck, so a cursed luckstone may still cause your actual Luck to be negative.

Gifts

If your prayer timeout is 0, you have positive alignment, and your god is not angry, you generally have a chance of getting an artifact. Your experience level must be at least 3, and your luck must be nonnegative.[40] If those conditions are met, the chances of your getting an artifact are 1 / (10 + 2 × Number of existing artifacts × Number of gifts granted by your god).[48]

If you receive an artifact, you get the message "An object appears at your feet!",[49] and your god will tell you to "use my gift wisely!"[50] Your wisdom is exercised,[51] your prayer timeout is set to rnz(300 + 50 × Number of existing artifacts),[52] and your skill in using the artifact's type of weapon becomes unrestricted.[53] The artifact will also be made erodeproof[54] and set to at least +0;[55] it will not be cursed.[56]

Your first gift will be a co-aligned artifact[57] that does not hate your current form.[58] Some roles have a guaranteed first sacrifice gift,[59] which is noted below; its alignment will be adjusted to your starting alignment at the beginning of the game if necessary.[60] Excalibur,[61] quest artifacts,[61] and cross-aligned artifacts cannot be gifted.[57]

Once a co-aligned artifact has already been given, then unaligned ones also become eligible.[62]

Lawful gifts: Demonbane, Grayswandir, Snickersnee (Samurai), Sunsword

Neutral gifts: Cleaver (Barbarian), Giantslayer, Magicbane (Wizard), Mjollnir (Valkyrie), Vorpal Blade

Chaotic gifts: Grimtooth, Orcrist, Sting, Stormbringer

Unaligned gifts: Dragonbane, Fire Brand, Frost Brand, Ogresmasher, Trollsbane, Werebane

Sacrificing creatures of own race

If the creature you sacrifice is of your own race, you get good effects if you're chaotic and bad effects otherwise.

If you are chaotic:
You gain five points of alignment.[63]
If the altar is chaotic, you gain two points of Luck, and if the altar is unaligned, you lose two points of Luck.[64] Your Luck is unaffected if the altar is cross-aligned (but the altar will be converted as noted in the cross-aligned altars section below).
If you are non-chaotic:
Your wisdom is abused unless you are polymorphed into a demon.[65] ("You'll regret this infamous offense!")
You lose five points of alignment.[66]
Your god's anger increases by three.[67]
Your Luck decreases by 5.[68]
You lose one point of wisdom.[69] This can be cured with a unicorn horn.
Outside of Gehennom, your god will punish you as for praying too much (depending on the level of anger).[70]
If the altar is chaotic, you'll destroy it and anger any attendant priest.[71]
Whether or not you are chaotic:
If the altar is chaotic or unaligned, a demon may be summoned. The demon will be peaceful if you are chaotic and hostile otherwise. The first two demons will be Juiblex and Yeenoghu in any order, followed by foocubi.[72]
If you are polymorphed into a demon, "You find the idea very satisfying."; your wisdom is exercised.[73]
If the altar is lawful or neutral, it will immediately be converted to chaotic (except on the Astral Plane),[74] independent of your alignment; if there is a priest tending the altar, they will be angered.[75]

The check for same race is done before the check for a former pet and ignores the check for age, so same-race corpses are always fit for sacrifice until they rot away completely. This is just about the only time an undead creature is a valid sacrifice.

Keep in mind that werecreatures are considered human, so sacrificing them if you're human will have the consequences described above.

Sacrificing pets

Sacrificing creatures that died while tame[76] will generally cause you to lose three points of alignment[77] and gain the aggravate monster intrinsic.[78] The pet will have a sacrificial value of -1,[79] so this will only result in the god of the altar being angered;[80] the corpse will not be consumed. Former pets that have gone feral no longer count as pets, and may be killed and sacrificed as usual.

Cross-aligned altars

(Level + 2) / (Level + 8)

You can convert cross-aligned altars (but not high altars[81]) by sacrificing at them if they're not unaligned altars in Gehennom.[82][83] If you fail, you will lose 1 Luck[84] and abuse wisdom.[85] If you succeed then you gain 1 Luck[86] and the altar becomes coaligned. The chances to convert an altar go up with character level. Converting an altar with a priest present will cause the priest to attack you.[87]

The probability to convert an altar is (Your level + 2) / (your level + 8).[citation needed]

In any case, minions may be summoned to protect the altar.[88][89]

When attempting to convert an altar, you will get the message "You sense a conflict between <your god> and <the god of the altar>." A successful conversion will produce the message "You feel the power of <your god> increase." A failed one will result in "Unluckily, you feel the power of <your god> decrease."

A sacrifice with negative value, such as a former pet, will not cause an attempted conversion. Instead, it will anger the altar's god, which will actually decrease your own god's anger by one.[90] You will still suffer the usual effects of angering a god, including the loss of any divine protection and being smitten by the angry god. The pet corpse is not consumed, so you can cure as much anger as you like.

Attempting to convert an altar while your alignment is negative[91] may convert your alignment to that of the altar,[92] take away 3 of your Luck[93] and increase your prayer timeout by 300[94] ("You have a sudden sense of a new direction"). This can only be done once per game on a non-unaligned altar;[95] if this happens before you have been admitted to the quest, the game will be unwinnable.

As with coaligned altars, if you get a message saying "Nothing happens", then the corpse was too old and, indeed, nothing happened.

Sacrificing unicorns

Sacrificing unicorns is complicated because the altar's alignment, your alignment, and the unicorn's alignment all factor into the outcome.[96] A unicorn's alignment is represented by its color. The white is lawful, grey neutral, and black chaotic. The points to remember are:

  • Never sacrifice a unicorn on an altar of its own alignment. You lose one point of wisdom and the altar's god becomes angry, with the same effect as angering that god through prayer.[97] If the altar is not of your alignment, your god's anger is reduced by one.[98]
  • Never sacrifice a unicorn of your own alignment. This increases your god's anger by one and acts as above if the altar is also of your alignment. If the altar is cross-aligned, this will set your alignment score to -1, which makes your sacrifice convert you instead of the altar.
  • If you have already been converted once before then an attempted conversion sacrifice will be rejected by the altar's deity (-5 to luck and alignment score, -2 to wisdom) and you will anger and be punished by your current deity.

Each time you sacrifice a unicorn of a different alignment on your own altar, you get a +5 boost to your alignment and the message "You feel appropriately {lawful | neutral | chaotic}", or "You feel you are thoroughly on the right path" if alignment is at maximum.

The rest of the effects are summarized in the following table:
