Noise
Some actions produce noise, waking sleeping monsters in a certain radius. Not all of them are actually auditory in nature, but for the sake of simplicity all are listed here. Most sources of noise do not rouse victims of temporary magical sleep (which is more akin to paralysis in nature). In general, you should avoid noise when dealing with crowds of naturally-sleeping monsters, such as in special rooms. The following events produce noise:
Event | Radius |
---|---|
Entering Fort Ludios while Croesus is still alive[1] | Entire level |
Aggravate (monster spell or effect)[2] | |
Entering a throne room, swamp, graveyard or treasure zoo for the first time, without stealth[3] | 1 in 3 chance for each monster on the level |
Turning undead[4] | Line of sight |
Reading a cursed or confused scroll of scare monster[5] | |
Using a drum of earthquake[6] | 41 |
Using a leather drum[7] | 6.3 × sqrt(XL) |
Using a tooled horn[8] or a bugle[9] | 5.5 × sqrt(XL) |
Using a tin whistle[10] or (50% chance) a cursed magic whistle[11] | 4.5 × sqrt(XL) |
Ringing a bell[12] | |
Zapping a wand or spell of digging into liquid[13] | |
Attempting to dig iron bars[14] | |
Kicking[15] | |
Attacking while polymorphed into a monster with an explosion attack[16] | |
Forcing a lock with a blunt weapon[17] | |
Making noise while fumbling[18] | |
Triggering an exploding trap on a door[19] or container[20] | |
Stepping on a squeaky board | 4.5 × sqrt(XL) for you,[21] 6.3 for monsters[22] |
Applying a polearm on a statue[23] | 5 around the statue |
Hurtle into a monster, a wall or other obstruction[24] | 3.2 (4.5 for iron bars) around the object |
Magical explosion (fireball, skilled cone of cold, destroyed wand)[25] | equal to base damage, but at least 7; quartered if engulfed |
Alchemical explosion[26] | 9 |
Monster attacking you with an explosion attack[27] | 7 around the monster |
Land mine explosion[28] | 20 around the mine |
Monster triggering a door trap[29] | 7 around the monster |
Opening a trapped door with the Bell of Opening[30] | 11 around the door |
Destroying a door with force bolt[31] | 4.5 (6.3 if trapped) around the door |
Destroying a drawbridge[32] | 22.4 around the drawbridge |
A boulder falling into liquid[33] | 6.3 around the fall |
Rock or boulder from a read scroll of earth hits a creature[34] | 4 around each hit |
One rolling boulder hits another[35] | 10 around the point of impact |
Monster cries after being hit with holy water[36]or a potion of acid[37] | 3.2 × sqrt(monster level) around the monster |
Gremlin cries after being hit with light[38] | 5.5 around the monster |
Monster growls[39] | 4.2 × sqrt(monster level) around the monster |
Monster whimpers[40] | 3.5 × sqrt(monster level) around the monster |
Monster yelps[41] | 2.4 × sqrt(monster level) around the monster |
Werecreature howls when chatted to[42] | 11 around the monster |
Giant shouts when chatted to[43] | 7 around the monster |
Any artifact dealing shock damage[44] (Mjollnir) | 16 around the monster |
Walking near a monster without stealth can also wake it up.[45] The monster must be in line of sight and within 10 squares; without aggravate monster there's only a 14% chance per monster move of it waking up. While this is presumably caused by you "making noise", it differs from above events in that the effect is continuous and is applied to each monster separately.
