Mind flayers and master mind flayers are especially perilous monsters, capable of eating your brain, resulting in feeling stupid, becoming forgetful ("This place looks familiar..."), or perishing as your last thoughts fade away. Wearing a helm, preferably greased, can sometimes protect you against the brain-eating attack. If you die from intelligence drain while polymorphed, you will permanently die instead of reverting to your normal form.
Polymorphing into a headless monster will protect you from the special attacks;[1] you will still suffer the normal weapon damage. Being polymorphed into a normally mindless form won't protect you; a comment says this is because players aren't mindless.[2]
If you manage to eat a mind flayer corpse, you gain either telepathy or 1 intelligence point, with a 50% chance of each.[3]
You can sense their presence remotely, and if you have telepathy they can sense yours. Occasionally they will concentrate and release a blast of psychic energy. If they are peaceful and you are not creating conflict, it will "feel quite soothing" and no harm will be done. Otherwise, if they can sense your presence either via telepathy or sight, it will "lock on" to your telepathy or mind, and you will sustain d15 damage (halved with half spell damage). This is the only attack in the game that you need to deal with if you are protected by a boulder/jelly combination fort.
Contents
Description
They have a humanoid body, with an octopus-like head, and four tentacles around a lamprey-like mouth.
Generation
Mind flayers generate randomly and are also candidates for being summoned by the summon nasties monster spell, but they are also notorious for generating in the Gnomish Mines when they are far too high difficulty to appear. This is because the Mines levels specify that one random h monster should be generated. This is almost always a dwarf, hobbit, or bugbear, but on occasion the function that chooses which h monster should be generated totally ignores the difficulty of the monster it produces. Flayers that generate like this are sometimes called minesflayers.
Strategy
Detection
Be careful not to run up to a mind flayer in melee thinking that it is a dwarf king; for some players, dwarves are easy kills while mind flayers are very dangerous. If you have felt the mind flayer's presence, that is your cue to check whether that h is a dwarf. The message "You sense a faint wave of psychic energy" is your clue that there is a (master) mind flayer somewhere on the level, but you won't see it every turn. Also note that dwarves will not be generated in Gehennom (but mind flayers may be generated in the Dungeons of Doom).
As pets
Advantages
Mind flayers make excellent pets, as they make quick work of shopkeepers, and their telepathic outreach just prints a useless message (which can be hidden with MSGTYPE) rather than harming you, or locks onto hostile monsters. However be careful if your tame mind flayer becomes confused—he will easily do the same with you.
Due to their high monster magic resistance, once a mind flayer reaches level 15, it will be immune to conflict, allowing you to have conflict active with no fear of your pet attacking you.
Disadvantages
In the late game, pet (master) mind flayers may wake up the Wizard of Yendor with their psychic blasts before you are ready to fight him, causing you a host of problems. It is best to be very careful with such a pet in the later parts of Gehennom where the Wizard's Tower might be.
Tame mind flayers may emit a "faint wave of psychic energy", which is indistinguishable from that of a hostile mind flayer. If "a wave of psychic energy pours over you", and it does not feel "quite soothing", there is a hostile mind flayer on the level.
Also, watch out for jellies, which can kill any mind flayer that attempts to suck its brains, as well as shapeshifters and green slime which your mind flayer may eat or attack.
Mind flayers can use all weapons and armor that the player can. If you want to protect your mind flayer against ochre jellies, which are frequently summoned in the later game, you might consider giving it any yellow dragon scales you come across, as these will give it acid resistance.
Combat
Be cautious when fighting against a mind flayer, and avoid melee if possible. Try to attack the mind flayer with ranged attacks. Those annoying master mind flayers can resist some magic attacks like force bolt, but you can still throw daggers or other weapons, or use more powerful spells like finger of death (if you can cast them).
Wear a greased helm. A non-greased helm has a 7⁄8 chance of preventing each of the mind flayer's tentacle attacks from reaching your brain. A greased helm always protects from the brain-eating, but each attack has a 1⁄2 chance of causing the grease to wear off. However, mind flayers get multiple attacks per turn, so you should not rely on this, especially if you are unable to kill the mind flayer quickly.
You may alternately want to wear a dunce cap or ring of sustain ability. Either will fix your intelligence, preventing its loss and thus brainlessness. The dunce cap, being a helm, also has a chance of blocking the flay altogether. However, neither will protect against amnesia from a successful brainsuck, and you're likely to come out of the fight very forgetful.
Engrave or burn Elbereth, or stand on a scroll of scare monster. Mind flayers respect Elbereth. However, Elbereth does not prevent them locking on to your telepathy.
Scare them by some other method, for example, an expensive camera. This is not as secure as Elbereth, as a fleeing mind flayer may still attack you, but it is much less likely to. Mind flayers' high magic resistance makes any resistible attack unlikely to succeed, and a blind mind flayer will not respect Elbereth.
Do not try to use cancellation against mind flayers; even if it gets through their magic resistance, their brainsucking attack will be unaffected.
Recovery
Obtain a unicorn horn. There are many other good reasons to have a unicorn horn, but you can apply one to recover your lost intelligence after the battle. This is of limited use during combat, however, as it has a chance of not restoring your intelligence when you use it, possibly resulting in death from brainlessness the next round. A unicorn horn will not cure amnesia. Some people collect a #named specimen of each identified object in their main stash to mitigate the effects of amnesia.
Special tactics
Stoning
It is possible to stone a mind flayer or master mind flayer. If you have a source of cockatrice corpses or eggs, or you find a cockatrice located conveniently near a mind flayer, wear gloves, wield the corpse (or egg), and strike the mind flayer in melee. It only takes one hit (unless the mind flayer eats a lizard corpse or ingests acid).
Taming
Mind flayers have high MR, so they're very likely to resist taming; the charm monster spell might or might not work. Be prepared to have the mind flayer attack you if your attempt of taming fails.
Genociding
Many players find the amnesia attack so crippling that genocide becomes the best option. A blessed scroll of genocide on h will wipe out both standard and master mind flayers. However, do not do this if you are a dwarf—dwarves are also h, and this self-genocide has resulted in a lot of annoying deaths. Instead, only use an unblessed scroll and genocide "mind flayer" or "master mind flayer".
If you can only genocide a single monster (e.g. from a throne), it is generally best to genocide the master mind flayer, as the summon nasties monster spell can conjure one right next to you. The standard mind flayer cannot be generated by this spell unless it randomly replaces a genocided or extinct nasty, so you will usually have a chance to deal with it before it gets in melee range.
Before using a scroll of genocide, check that it is not cursed. If you send in a group of master mind flayers, they may kill you quickly, either by causing brainlessness in a few short turns, or (if you scare them away) by possibly locking on to any telepathy you possess until you die. This may also leave an annoying bones level.
Polymorphing
Polymorphing into a master mind flayer is very useful, as its brain-eating attack is deadly to nearly anything. Monsters do not suffer brainlessness in the manner that players do, as they lack intelligence scores. When a player eats a monster's brain, it instead deals an additional d10 points of damage to simulate the brain loss. Additionally, you will gain d30 nutrition per suck message without risk of choking, and if your intelligence score is below the maximum (i.e. your own brain was sucked) it will be increased by d4. The intelligence increase is subject to the normal polymorphed attributes rules, and will be reset when you revert to your normal form.
Sucking a green slime causes delayed sliming, and eating a cockatrice's brain causes both immediate stoning and delayed stoning (if the immediate stoning was life-saved). Sucking the brains of your race or other mind flayers will count as cannibalism as well. Eating brains is also not considered vegetarian, but this is only of interest to conduct players and Monks.
Becoming a master mind flayer also gives you a +10 base AC boost and still allows you to wear all the same equipment you were wearing before, which is unique among the better fighter forms; you can also carry exactly as much as in your natural form. On top of that, master mind flayers can fly and attack many times per turn, which dealss excellent damage to non-mindless enemies. Your HP will most likely drop significantly, especially if you polymorph yourself at a high level.
History
In NetHack 3.4.3 and previous versions, the game would not recognize the alternate spelling "mindflayer" when selecting a monster for genocide. A Monk that attempted to genocide "master mindflayer" would instead genocide "master", thus wiping out all Monks and ending the game. This is because "master" is one of the rank titles for Monks, and NetHack ignores the extra word "mindflayer".[4] Both NetHack 3.6.0 and SLASH'EM recognize the "mindflayer" spelling, so it is okay to genocide "master mindflayer" in those games, but a typo like "master mindfalyer" can still wipe out all Monks and end the game.
SLASH'EM
Mind flayers are slightly different in SLASH'EM. First, the master mind flayer has three brain-eating attacks, while the normal mind flayer has five—an unusual reverse of the situation in vanilla NetHack. More importantly, though, the ring of free action provides luck-based protection against their brain-eating attacks, starting at a 50% of blocking each individual flay and increasing to a 90% chance at maxed-out luck.[5] This, in combination with a greased helm, renders them much less of a threat.
Also, SLASH'EM introduces more sources of amnesia (such as potions of amnesia and migo queen attacks), making a preventative genocide of mind flayers much less of a surefire protection against amnesia.
Lastly, if you polymorph into an intelligent monster in SLASH'EM, generally you need not worry about petrifying monsters. This is true of mind flayers—instead of eating the cockatrice's brain and being stoned, you will instead simply not use your tentacle attack against it at all. Your weapon attack will still go forward, though, and it is still possible to get stoned by other methods (e.g. attacking it bare-handed).
Mythology
Mind flayers appear in Dungeons & Dragons as Illithids. D&D's creator, Gary Gygax, was reportedly inspired to create the monster after seeing cover art for a book by Brian Lumley.
Encyclopedia entry
This creature has a humanoid body, tentacles around its
covered mouth, and three long fingers on each hand. Mind
flayers are telepathic, and love to devour intelligent beings,
especially humans. If they hit their victim with a tentacle,
the mind flayer will slowly drain it of all intelligence,
eventually killing its victim.
