A potion of speed is a type of potion that appears in NetHack.


Randomly generated monsters may receive a potion of speed as a miscellaneous item, with a 56 chance of one appearing in a monster's starting inventory if a speed item is chosen.[1]


Quaffing a potion of speed temporarily grants very fast speed and heals wounded legs, and will auto-identify the potion unless you already have very fast speed. The duration of higher speed depends on the potion's beatitude:

  • Blessed: 160–169 turns
  • Uncursed: 100–109 turns
  • Cursed: 40–49 turns

Quaffing the potion while already very fast adds the number of turns to the current duration, if applicable. Inhaling vapors from a shattered potion gives you 1-5 turns of very fast speed and prompts you to type-name the potion.

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Quaffing a non-cursed potion of speed gives permanent intrinsic speed in addition to the temporary intrinsic. (commit 95972d71)


Early in the game, a potion of speed allows you to outrun enemies you either aren't ready for or need separation from (e.g., Team Ant), or pummel enemies that have you trapped - even cursed potions are worth drinking in this regard.

If you find or decide to wish for speed boots later on, these potions become viable candidates for alchemy: they are typically preferred for upgrading healing potions to extra healing potions, and this also works for dipping a stack of them in a potion of healing. Even with speed boots, potions of speed can still be worth holding on to, especially for the endgame: If you decide to swap your speed boots for jumping boots on the Astral Plane, a potion of speed will allow you to remain very fast - this increases the chances of being able to jump through a path cleared with a zapped wand of teleportation before monsters can reoccupy it.


The potion of speed has been present in the game since Hack 1.21, a variant of Jay Fenlason's Hack, and is one of the initial items that appears in Hack 1.0.


You are suddenly moving much faster.
You gained very fast speed from quaffing the potion.
Your legs get new energy.
You extended the duration of very fast speed by quaffing the potion.
Your knees seem more flexible now.
You inhaled the vapors from a shattered or boiled potion of speed.



In SLASH'EM, two potions of speed can be found in the outside area of Grund's Stronghold, and four more are placed within the stronghold itself.


In xNetHack, the potion of speed gives intrinsic speed and a short duration of very fast speed, making it the replacement for the wand of speed monster (which grants temporary very fast speed) as an intrinsic speed source; potions of speed are also less likely to be used for alchemy as a result.


In EvilHack, the Paladin is always generated with a potion of speed.


In SlashTHEM, in addition to SLASH'EM details, brewing a potion of speed using a chemistry set uses up three charges.
