Potion

Version 0.29: This article may not be up to date for the latest stable release of Crawl.

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 during -Potion (after being damaged with the No Unsafe Potions mutation).

Potion Identification

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

You may guess at a potion's identity by the size of the stacks in your inventory. Potions of curing and potions of heal wounds are the two most common types of potions. Note that potions can come in batches of 2 or 3, which are treated as one item for purposes of rarity. This is, of course, nonconclusive - but may be useful to know in a dire situation.

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, with effects that do not wear off by simply passing turns.

Monsters will sometimes drink potions within your line of sight; this identifies the potion, if it was unidentified.

Some more notes on potion identification:

• Many backgrounds begin play with an identified potion.
• Certain vaults may contain pre-identified items.
• The Sewer will often contain some potions of flight.
