'''Potions''' are useful consumable items represented by the <nowiki>'</nowiki>'''!'''<nowiki>'</nowiki> character. Every potion has a specific effect (beneficial or harmful!) when [[quaff]]ed. You can't drink potions while [[berserk]], in [[bat form]], [[wisp form]], [[tree form]], [[fungus form]], or [[lich form]], or if you're a [[mummy]].

Drinking most potions will increase your [[satiation]] by 40 points, except for [[vampire]]s (who only get satiation from [[potions of blood]] and [[potion of coagulated blood|coagulated blood]]). The primary effect of most potions is halved for Thirsty (or worse) Vampires.

Apart from using a [[scroll of identify]], there are several ways to determine the identity of potions you've picked up.
  
Some race/class combinations begin with potions identified. [[Spriggan]]s recognize potions of porridge, [[vampire]]s recognize potions of blood, [[assassin]]s recognize [[potions of poison]], [[healer]]s recognize potions of curing and heal wounds, and [[wanderer]]s may start with some identified potions in their inventory. Wanderers also have a chance to recognize potions of curing regardless of inventory.

Some race/class combinations begin with potions identified. All characters recognize potions of blood, [[fighter]]s start with a [[potion of might]], and [[wanderer]]s may start with some identified potions in their inventory.
 
   
 
   
Quaffing a random potion is the most obvious way to figure out its contents, but may be dangerous. You'll want to be somewhere safe with no monsters in sight, and if possible, with some already identified [[potions of curing]] on hand to cure the worst offenders ([[potions of poison]], [[potions of strong poison]], and [[potions of decay]]). [[Potions of degeneration]] and [[potions of mutation]] are also harmful, and those are less likely to be easily remedied.

Quaffing a random potion is the most obvious way to figure out its contents, but may be dangerous. You'll want to be somewhere safe with no monsters in sight, in case of a [[potion of ambrosia]], [[potion of lignification]], or [[potion of berserk rage]]. [[Potions of degeneration]] and [[potions of mutation]] are also harmful, but those effects do not wear off by simply passing turns.
  
Monsters sometimes drink potions within your [[line of sight]]. This will identify the potion in most cases, but there is sometimes ambiguity with healing, in which case the potion type will be inscribed with '''{tried by monster}'''. When this happens, the potion is either a potion of curing or heal wounds, or rarely blood/coagulated blood (if a [[list of vampires|vampire]] drank it).

Monsters sometimes drink potions within your [[line of sight]]. This identifies the potion.
  
You may also guess at a potion's identity by the size of the stacks in your inventory. Potions of curing are the most frequent (about 25% of all potions generated), followed by potions of heal wounds (about 13% of all potions generated). This is very unreliable if your highest potion stack is only 2 or 3 since potions are sometimes generated in batches. On the other hand, [[potions of porridge]], [[potion of gain strength|gain strength]], [[potion of gain dexterity|gain dexterity]], [[potion of gain intelligence|gain intelligence]], [[potion of cure mutation|cure mutation]], [[potion of experience|experience]] and [[potion of decay|decay]] are very rare (less than 1% of all generated potions), so you're unlikely to pick one of those if you only drink potions when you have two of the same type.

Some more notes on potion identification:
*A potion found in a small pile (2 or 3 potions) will never be a potion of gain strength, gain dexterity, gain intelligence, experience, or [[potion of restore abilities|restore abilities]]. However, some special [[vault]]s such as [[bailey]]s can contain multiple potions of gain stats or cure mutation in separate piles.
+
*If you find an altar of Cheibriados surrounded by 2 potions and 2 fruits, these potions are either [[potions of lignification]] or [[potions of haste]].
*Potions of strong poison are never randomly generated before level 11.
+
*A certain entry [[vault]] for the [[Orcish Mines]] has multiple potions scattered about in addition to several placed behind a door. Most of them are [[potions of degeneration]].
*Potions of blood are always red potions (25% viscous red, 25% sedimented red, 50% red) and are dropped by vampires.
+
*The [[Sewer]] will often contain some [[potions of flight]].
**Potions of coagulated blood are always gluggy, lumpy, sedimented, or viscous, and are either red or brown.
 
**Carrying an unidentified potion of blood for at least 2000 turns will turn it into a potion of coagulated blood, identifying both potions in the process.
 
*Potions of porridge are either gluggy white or gluggy brown.
 
*If you find an altar of Cheibriados surrounded by 2 potions and 2 fruits, these potions are either [[potions of slowing]] of [[potions of speed]].
 
*A certain entry [[vault]] for the [[Orcish Mines]] has multiple potions scattered about in addition to several placed behind a door. All of these are bad potions (such as slowing or paralysis).
 
 
 
==Potion Conservation==
 
[[Ice Magic]] and other sources of [[cold]] damage may shatter the potions in your inventory; the [[conservation]] intrinsic reduces the chance of this happening. You can obtain conservation through an [[amulet of conservation]], [[cloak of preservation]], [[Jiyva]], [[Maxwell's Patent Armour]], or a rare [[demonspawn mutation]].

Version 0.21: This article may not be up to date for the latest stable release of Crawl.

This page is about the Item. For the card, see Potion card

An unlabeled flask containing a single dose of unknown liquid.

"Then gave I her, - so tutor'd by my art, -
A sleeping potion, which so took effect
As I intended, for it wrought on her
The form of death: meantime I writ to Romeo
That he should hither come as this dire night,
To help to take her from her borrow'd grave,
Being the time the potion's force should cease."

-William Shakespeare, _Romeo and Juliet_

Potions are useful consumable items represented by the '!' character. Every potion has a specific effect (beneficial or harmful) when quaffed. You can't drink potions while berserk, in lich form, if you're a mummy or if you have sacrificed Drink as a Ru worshipper and are injured badly enough.

Potion Identification

Apart from using a scroll of identify, there are several ways to determine the identity of potions you've picked up.

Some race/class combinations begin with potions identified. All characters recognize potions of blood, fighters start with a potion of might, and wanderers may start with some identified potions in their inventory.

Quaffing a random potion is the most obvious way to figure out its contents, but may be dangerous. You'll want to be somewhere safe with no monsters in sight, in case of a potion of ambrosia, potion of lignification, or potion of berserk rage. Potions of degeneration and potions of mutation are also harmful, but those effects do not wear off by simply passing turns.

Monsters sometimes drink potions within your line of sight. This identifies the potion.

You may also guess at a potion's identity by the size of the stacks in your inventory. Potions of curing are the most frequent (about 25% of all potions generated), followed by potions of heal wounds (about 13% of all potions generated). This is very unreliable if your highest potion stack is only 2 or 3 since potions are sometimes generated in batches. On the other hand, potions of experience are very rare (less than 1% of all generated potions), so you're unlikely to pick one if you only drink potions when you have two or more of the same type.

Some more notes on potion identification:

History

0.20 merged potions of beneficial mutation, potions of cure mutation, and potions of mutation.

0.18 removed potion of poison.

0.17 removed potion of decay and potion of restore abilities. It also made any potion able to be found in a stack, so that information can no longer be used to narrow down the possibilities. Monster quaffing always identifies a potion. Potions of curing and heal wounds now heal rot first, instead of last; effectively, rotting reduces the effectiveness of healing until cured. The Rot status is also gone, with rot taking place immediately.

0.16 removed potion of coagulated blood, potion of confusion, and potion of porridge. It added potion of ambrosia.

0.15 removed potion of strong poison and potion of paralysis. Potion of cancellation was added. Prior to this version, thirsty vampires received only half the effect from most potions.

As of 0.14, the basic 40 satiation for all potions was removed, and the potion of slowing was replaced with the potion of lignification. Potions of speed are known as Potions of haste. Known potions that would have no effect can no longer be quaffed.

Prior to 0.13, instead of potions of beneficial mutation, there were the potions of gain stat, which gave (as a mutation) increases to individual stats.

Prior to 0.12, you could throw potions to generate cloud attacks against enemies with the Evaporate spell. You could also identify several unpleasant potions by creating samples of them through Fulsome Distillation.
