Scare
In NetHack, scaring monsters causes them to flee, which can be useful in many cirumstances. A fleeing monster will generally try to move away from your position in a random direction. However, it can still use ranged attacks, including offensive wands and breath weapons - it will even use melee attacks if the monster happens to be next to you and cannot get away. Followers that are scared will not pursue you down or up stairs.
Technically, NetHack has two different properties: "scared" and "fleeing", with the fleeing behavior being what players generally see. A fleeing monster has a 1⁄25 chance of recovering per monster move, unless it has a predetermined duration.[1] A monster that is "scared" cannot attack; this status property can be seen via probing (e.g. by a stethoscope). It typically lasts as long as the monster is next to Elbereth, the player is playing a tooled horn, or similar.[2]
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.

Stand on a dropped scroll of scare monster[5] | N | 1–10 (6⁄7) 1–100 (1⁄7) |
Fast deployment. Portable. Using it does not break illiterate conduct. | Requires suitable terrain. Needs to be re-blessed to be reusable. Can be burned by fire. Does not work on the Wizard of Yendor, A angelic beings, or & Riders. |
Read a noncursed scroll of scare monster[6] | Y | Untimed | Can affect any monster. | Uses up scroll. Breaks illiterate conduct. |
Cast cause fear[7] | Y | Untimed | Can affect any monster. | |
Improvise on a tooled horn or an uncharged frost horn or fire horn[8] | Y | Untimed | Always available once acquired. Can affect any monster. Works while engulfed. Tool can be used to play passtune. | Awakens sleeping monsters. Instruments cannot be used underwater. Abuses wisdom. |
Apply a leather drum[9] | Y | Untimed | Always available once acquired. Can affect any monster. Works while engulfed. Larger area of effect than a tooled horn. | Awakens sleeping monsters. Instruments cannot be used underwater. Abuses wisdom. |
Apply a drum of earthquake[10] | Y | Untimed | Affects entire level when charged. Works while engulfed. Works as leather drum once charges are used. | Creates an earthquake when charged. Awakens sleeping monsters. Instruments cannot be used underwater. |
Blind a monster by applying an expensive camera or breaking a wand of light[11] | N | 1–100 (1⁄4) Untimed (3⁄4) |
Constant 25% chance of failure. Does not affect shopkeepers, y lights, A archons, or monsters that are blind, have no eyes, or are protected from blinding by an artifact. Attack blinds the affected monster. Cameras cannot be used underwater. | |
Apply a mirror at a monster[12] | N | 2d4 | Always available once acquired. Some useful special cases. | Cannot affect humanoid monsters, blind monsters (with or without eyes), u unicorns, or sleeping monsters. Constant 20% chance of failure. Some useless special cases. Mirrors do not work underwater. |
Hit the monster with Magicbane[13] | Y (1⁄2) N (1⁄2) |
3 | Always available once acquired. Can affect any monster. Works while engulfed. | The effect occurs only occasionally, and you cannot choose when. |
Use turn undead ability[14] | Y | Untimed | Available only to Priests and Knights. Cannot be done in Gehennom. Works only on L M W V Z , as well as i and & if the player is level 16 or higher. Will destroy undead instead at higher experience levels. Makes you helpless for 5 turns, and you can be freely attacked by non-undead monsters during that time. It is therefore usually a good idea to engrave Elbereth before you begin using this ability. | |
Zap wand of undead turning or cast turn undead[15] | Y | Untimed | Works only on L M W V Z undead. | |
Hit undead with a clove of garlic[16] | N | 2d4 | Works only on L M W V Z undead. | |

Happens only 4% of the time. | |
Shatter a monster's weapon[21] | N | 2d3 | Shattering occurs at most 2.5% of the time, less if your weapon is eroded, and even upon a successful shattering the monster only flees 75% of the time. You must be wielding a two-handed weapon and be at least skilled, or be a Samurai wielding a katana with nothing in your other hand. | |
Cause a monster to use a defensive item or dungeon feature[22] | N | 3–33 (depends on hit points) | Usually you don't want the monster to use up (charges in) its items. | |

Encounter a l leprechaun with more gold than you[24] | N | 2 | Leprechauns are not technically scared, however the intent and result are similar to the case of stealing an item, and much of the movement code is shared. It is harder to acquire the leprechaun's gold, and leprechauns are rarely dangerous anyway. | |
Encounter a ; sea monster out of water[25] | N | 2 | These creatures are vulnerable when out of water and always flee when they are. | These creatures are only ever generated to initialize watery levels. The only time you are likely to see them out of it is due to a polymorphed monster or reverse genocide. |

Effect
If you are grabbed or engulfed by a monster, scaring it will cause it to release or expel you.[30]
A fleeing monster will usually try to get further away from you[31] unless it is trapped[32] or eating.[33] However, it will retrace its steps only around 25% of the time;[34] if you scare a monster in a narrow corridor, it will have nowhere to go and just stand still, attacking you.[35]
The following monsters have special code to handle their movements, and will not always move away from you while scared:
- pets[36]
- shopkeepers[37]
- @ guards[38]
- covetous monsters[39]
- @ aligned priests[40]
A fleeing monster may attack you in melee if it blunders into you when you are invisible or displaced, or if it is confused, stunned, blinded,[41] or cornered. Monsters will never melee when adjacent to a square they think is protected by sanctuary, Elbereth, or a scroll of scare monster (or an altar if a vampire).[42]
Monsters will still use ranged attacks while fleeing.
A monster will stop fleeing when any time has expired. If the scaring is untimed, it will stop fleeing 4% of the time on each move it makes, if its hit points are at maximum.[43]
Strategy
There is no single perfect method of scaring enemies; all methods either allow monsters to resist or have significant exceptions. Thus it pays to keep multiple methods available. For example, sanctuary or Elbereth will not scare a ki-rin, but because this angelic being is not humanoid, applying a mirror will scare it 80% of the time. A high-level player might scare it with a spell of cause fear, but this will be successful less frequently than the humble mirror.
Typically, you can rely on Elbereth in the early game, until you start meeting hostile @ humans or elves. Lower-difficulty monsters in this group typically have little or no magic resistance and can be scared by an instrument, spell, or wand. Later in the game, higher-difficulty A angelic beings and @ humans or elves have higher resistance and are thus harder to scare; however, at that point you will not need to scare monsters as often in order to survive.
The utility of scaring a monster depends on its behavior. If you want to avoid a monster's melee attack, scaring is is very useful. This makes it ideal for creatures such as c cockatrices and h master mind flayers. Once you have magic resistance and cold resistance, however, scaring an L arch-lich is of dubious benefit.
