'''Potions''' are [[magic]]al drinks. They are denoted by an exclamation mark, '''!''' and [[weight|weigh]] 20. Some of them are very useful, some can be deadly. The effects of potions can often be determined by drinking them or breaking them onto somebody by [[throw]]ing it at them. Some potions can also be mixed together to form new potions &mdash; that is called [[alchemy]].

A [[Unicorn horn]] can be used to help in [[identification|identifying]] potions.

[[Smoky_potion|Smoky]] and [[Milky_potion|Milky Potions]] are special. A smoky potion has a chance of containing a [[djinni]], while quaffing a milky potion may release a hostile [[ghost]].

The table is divided into price groups. See [[price identification]].

==Generation==

Potions comprise 16% of all randomly-generated items in the main dungeon, 18% in containers, 22% on the [[Rogue level]], and 1% in [[Gehennom]].<ref>[[mkobj.c#line30]]</ref> Potions appear 1/8 cursed, 3/4 uncursed, and 1/8 blessed.<ref>[[mkobj.c#line545]]</ref>

On top of random generation, potions can be found in [[shops]], in [[bones]] files, and amongst the possessions of recently deceased monsters.

Because of each potion's likelihood of being created, drinking a random potion will have a harmful effect about 31% of the time, a useless effect 15% of the time, and a at least midly benficial effect about 54% of the time. A random potion taken from your inventory will have a 13.4% chance of increasing your health, if you are in [[Things To Do If You're Going to Die Next Turn|immediate danger of dying]].

==Identification==

With the exception of potion of water (which is always clear), potions always take a random appearance from the following list:

    ruby        pink        orange        yellow          emerald
    dark green  cyan        sky blue      brilliant blue  magenta
    purple-red  puce        milky         swirly          bubbly
    smoky       cloudy      effervescent  black           golden
    brown       fizzy       dark          white           murky

Regardless of their properties, smoky and milky potions are special in that the former may contain a [[djinni]] and the latter a [[ghost]].

==Damage==
Fire and cold attacks can cause potions carried in your main inventory to boil or freeze and be destroyed. This does not happen to potions carried in a [[container]], so it is generally advisable to carry potions that way when possible.

Potions boiled by fire attacks are vaporized, which can subject you to the effects of the [[vapors]].  Potions frozen by cold attacks will not release any vapors.

==Dilution==
Most potions will become diluted when they get [[wet]], either through immersion in open water, or [[dip | dipping]] into open water, a fountain, or another potion (in [[alchemy]]).  Note that this will not happen when dipping into [[holy water]] or [[unholy water]]--those potions change the [[beatitude]] of the dipped item without actually getting it wet, and are consumed in the process.  Hey, they're magic.

Diluted potions are listed as such in your inventory, and they will not stack with non-diluted potions.  This can be a minor hassle if your intention is to bless a group of potions with holy water, or if you have no [[container]] and inventory slots are at a premium.  But otherwise, diluted potions function largely as full-strength ones do.  There are some exceptions, mostly minor, which include:
*A diluted [[potion of booze]] will not cure 1HP of damage, as a non-diluted one will.
*A diluted [[potion of see invisible]] will give somewhat different messages, though the effect is the same.
*A diluted [[potion of fruit juice]] gives half the nutrition of a non-diluted one.

If a diluted potion is diluted a second time, it will lose any blessed or cursed status, and become an uncursed [[potion of water]].  This is a vital step in the production of [[holy water]], an activity that will occupy most characters to some extent for much of the game.  Even otherwise useless or harmful potions become a vital resource when considered in this light.

This is NetHack, so naturally there are some exceptions to the above principles:
*A [[potion of acid]] will not dilute, but instead cause an explosion that does damage to the character.  If your character dies as a result of this, the cause of death will be listed as "elementary chemistry." (Acid can be used as a weapon, a cure for [[stoning]], or turned into water via [[cancellation]].)
*A [[potion of water]] can not be diluted, which is not surprising, but this means that holy water and unholy water are also immune to dilution, as they are simply blessed or cursed potions of water, and losing beatitude is a consequence of dilution.
*Alchemy will not dilute an already-diluted potion.  So it is safe to convert a [[potion of healing]] into a diluted [[potion of extra healing]], and this into a diluted [[potion of full healing]]--this will not leave you with a very expensive potion of water.

[[Alchemy]] is a somewhat complicated process which has a few wrinkles of its own.  Players are advised to study that article before alchemizing unless they enjoy picking imaginary shards of glass out of their faces.

==Hitting and Being Hit==
Potions may be [[wield]]ed or [[throw]]n in combat, by you or by monsters against you.  A monster has an 80% chance of taking 1 HP of damage when hit (but will not be killed by this); you receive 1 to 2 HP, and, of course, you ''can'' be killed this way.  If you don't see the potion hit the monster, you will get the message "Crash!"  Whoever is hit by a potion will be affected by the potion, but generally to a lesser extent than from quaffing it. However, a thrown potion has a chance to miss the target, in which case it will shatter without affecting the the target. When a potion shatters, it is possible for the [[vapors]] to affect the player, if standing in an adjacent square. For this reason, wielding a potion hand-to-hand can be riskier than thowing it from a distance, although in this case the potion will only shatter when it hits the monster.  Circumstances might dictate the choice to throw vs. wield a potion, for instance, someone wearing a [[ring of free action]] and wielding a [[potion of paralysis]] would be able to reliably paralyze a non-resistant foe.

==Properties of Potion Bottles==
Potions, or rather the bottles they come in, are one of the more remarkable types of objects in the world of Nethack. Potion bottles are not watertight, because falling in water while carrying them dilutes them. And yet they don't ordinarily spill or leak, because you can carry them for tens of thousands of turns and even fall down stairs without any risk of this happening. The bottle, presumably, evaporates or shatters or otherwise is destroyed when the potion is drunk, or else it could be refilled at any fountain for a practically inexhaustable supply of [[holy water]]. This must also happen when the potion freezes, or else you could simply wait for it to thaw. Perhaps it is the bottle that is magical, as much as or more than the colored liquid within.

{{encyclopedia|
POTABLE, n.  Suitable for drinking.  Water is said to be
potable; indeed, some declare it our natural beverage,
although even they find it palatable only when suffering
from the recurrent disorder known as thirst, for which it
is a medicine.  Upon nothing has so great and diligent
ingenuity been brought to bear in all ages and in all
countries, except the most uncivilized, as upon the
invention of substitutes for water.  To hold that this
general aversion to that liquid has no basis in the
preservative instinct of the race is to be unscientific --
and without science we are as the snakes and toads.
