A potion of fruit juice is a type of non-magical potion that appears in NetHack, and is juice from the nameable fruit.

Generation

Wizards may be given a potion of fruit juice as any of the three random potions in their starting inventory.

Potions of fruit juice make up ²¹⁄₅₀₀ (4.2%) of all randomly-generated potions.

General stores, liquor emporiums, delicatessens, and health food stores can sell potions of fruit juice—each item in a delicatessen has a ¹⁄₂₀ chance of being a potion of fruit juice, while each item in a health food store has a ¹⁄₅ chance of being a potion of fruit juice.

Fruit juice can be created from other potions through the following methods:

• Dipping an amethyst into a potion of booze produces fruit juice.
• Dipping a unicorn horn into a potion of sickness produces fruit juice.
• Cancelling a potion of sickness or see invisible produces fruit juice.
• Mixing a potion of healing, extra healing, or full healing with a potion of sickness can create fruit juice.

Applying a horn of plenty has a ⁷⁄₅₀₀ chance (1.4%) of generating 1-2 potions of fruit juice.

Description

Quaffing a potion of fruit juice raises the hero's nutrition: the potion grants 10 nutrition if cursed, 20 if uncursed and 30 if blessed, and the amount is halved if the potion is diluted. Quaffing fruit juice does not break foodless conduct.

Strategy

Potions of fruit juice offer minimal nutrition per unit of weight compared to other comestibles, while weighing the same 20 aum as a food ration—most heroes will dliute known fruit juice into water, quaff them immediately, or else use them for polypiling. In a game where the smoky potion is fruit juice, players may consider going for wishes by collecting potions of sickness, booze, or see invisible to turn into fruit juice.

Foodless conduct players may consider seeking out these potions to maintain their nutrition, and also benefit from alchemizing diluted fruit juice into booze in particular.

Identification

The potion of see invisible uses the same messages as fruit juice when quaffed, making it somewhat difficult to tell them apart. In addition to the generation rules above, some ways to reliably identify fruit juice and distinguish it from potions of see invisible include:

• Since fruit juice is sold in delicatessens and health food stores, you can narrow down their appearance by dropping a suspected potion of either type on an applicable shop square.
• As mentioned above, dipping a unicorn horn into a potion of sickness turns it into fruit juice, allowing it to reliably be type-named.
• Fruit juice is unaffected by cancellation.
• If you have become hungry within the last few turns and that status disappears upon quaffing one of these potions, that potion is fruit juice.

History

The potion of fruit juice first appears in Hack 1.21, Hack for PDP-11 and PC/IX Hack, which are all based on Jay Fenlason's Hack. It is included in the initial item list for Hack 1.0.

Messages

The following messages use whatever the user-specified name for the fruit is, which is "slime mold" by default.

This tastes like <slime mold> juice.

The potion was blessed or uncursed.

Yecch! This tastes rotten.

The potion was cursed.

This tastes like reconstituted <slime mold> juice.

The potion was diluted.

This tastes like 10% real <slime mold> juice all-natural beverage.

You quaffed the potion while hallucinating.

This tastes like 10% real reconstituted <slime mold> juice all-natural beverage.

As above, and the potion was diluted.

Variants

Variants that implement gem alchemy do not change the ability of amethysts to turn booze into fruit juice.

SLASH'EM

In SLASH'EM, vampire heroes in roles that start with potions of fruit juice will have them replaced with potions of blood, though in practice this only applies to vampire Wizards that are given fruit juice among the random potions in their starting inventory.

Mixing a potion of blood or a potion of vampire blood with potions of fruit juice will respectively turn the fruit juice into more regular or vampire blood.

All of the above information also applies to SlashTHEM.

UnNetHack

UnNetHack uses the same substitution of potions of blood for fruit juice in the starting inventory of a vampire hero as SLASH'EM.

Also like SLASH'EM, Mixing a potion of blood or a potion of vampire blood with potions of fruit juice will similarly turn the fruit juice into regular blood or vampire blood—as UnNetHack employs a color alchemy system, these are the only fixed recipes present in the game.

dNetHack

In dNetHack, notdNetHack and notnotdNetHack, incantifier heroes in roles that start with potions of fruit juice instead receive scrolls of food detection, which in practice only applies to incantifier Wizards that are given fruit juice among the random starting potions. Vampire heroes in the same roles are given potions of blood, which will always be human blood.

Mixing a potion of a monster's blood with potions of fruit juice will turn the fruit juice into more blood if the blood used is not acidic.
