A '''scroll of stinking cloud''', which costs 300 zorkmids, allows you to center a cloud of [[poison]] gas around a point of your choice on the dungeon map.

When read, the scroll will [[auto-identify]] and prompt you to select a square on the dungeon map; the scroll will attempt to center a cloud of [[poison cloud|poison gas]] around the chosen square, with its size and damage depending on the scroll's [[beatitude]]. The selected square must be visible and within a range of 5.6 tiles for the cloud to be successfully placed; selecting a square outside of this range will print a message and use up the scroll, with no other effect.{{refsrc|src/read.c|961|nethack=3.6.7}} Blessed scrolls will create a larger cloud and do more damage; cursed scrolls give a smaller cloud and do less damage.

==Effects==

The stinking cloud causes damage and angers monsters, save those that are [[nonliving]] or [[unbreathing]]. [[Poison resistance|Poison resistant]] monsters do not take damage, but are still angered. Monsters with eyes are [[blind]]ed.{{refsrc|region.c|929}}

The lifespan of the cloud is dependent upon the [[BUC]] status of the scroll; after 4–6 turns, a cloud created by a cursed scroll will disappear, while a cloud created by a non-cursed scroll will undergo a first dissipation, after which it will cause less damage. Then, after two more turns, a cloud created by an uncursed scroll will disappear, while a cloud created by a blessed scroll will undergo a second dissipation, after which it will cause even less damage. Then the cloud will disappear. Thus, the total lifespan of the cloud is 4–6 turns for a cursed scroll, 6–8 turns for an uncursed scroll and 8–10 turns for a blessed scroll.

cursed#/uncursed#/blessed# cloud size

When read, the scroll will auto-identify and prompt you to select a square on the dungeon map; the scroll will attempt to center a cloud of poison gas around the chosen square, with its size and damage depending on the scroll's beatitude. The selected square must be visible and within a range of 5.6 tiles for the cloud to be successfully placed; selecting a square outside of this range will print a message and use up the scroll, with no other effect.[1] Blessed scrolls will create a larger cloud and do more damage; cursed scrolls give a smaller cloud and do less damage. Reading the scroll while confused does not change the effect.

Scroll BUC Damage before dissipation (for 4–6 turns) Damage after 1st dissipation (for 2 turns) Damage after 2nd dissipation (for 2 turns) Cloud size
Blessed 6–17 6–11 6–8 4×4
Uncursed 6–13 6–9 (cloud gone) 3×3
Cursed 6–9 (cloud gone) (cloud gone) 2×2

The lifespan of the cloud is also dependent upon the beatitude of the scroll: the total lifespan of the cloud is 4–6 turns for a cursed scroll, 6–8 turns for an uncursed scroll and 8–10 turns for a blessed scroll. A cloud created by a non-cursed scroll will undergo a first dissipation, after which it will cause less damage; after two more turns, a cloud created by an uncursed scroll will disappear, while a cloud created by a blessed scroll will undergo a second dissipation, during which it will cause even less damage before eventually disappearing.

The area covered by a stinking cloud is represented by #Cloud.png - monsters caught in the cloud (including you) will take damage unless they are nonliving, unbreathing or have poison resistance, and will be blinded if they have eyes.[2][3] Peaceful monsters caught in the poison gas will become hostile regardless of if they took damage from it. Monsters killed by a poison cloud created from a scroll you read count as being killed by you for purposes of benefits such as gaining experience, as well as applicable penalties including murder.[4]

Strategy

Players who are unbreathing or poison resistant can use the scroll of stinking cloud to wipe out an entire crowd of surrounding monsters. Players can also use the scroll to target packed rooms like treasure zoos and throne rooms and wipe out many monsters from a distance, with most of them being unable to move away from the cloud. This works especially well in Fort Ludios's throne room.

A stinking cloud can also be used to kill a shopkeeper from a safe distance, provided you are magic-resistant—the cloud should kill the shopkeeper before they use up their wands and come after you physically, all the while blinding them and forcing them to use up their potions of healing or extra healing to un-blind themselves. The shopkeeper seems to stand still inside the cloud as long as they cannot see you.
