5e - Alternatives to Darkvision

Darkvision is fairly common among the character races in D&D 5e.

Dwarves have it, elves have it, gnomes have it, half-elves and half-orcs have it, and so do tieflings. Only humans, halflings, and dragonborn don't, at least among the races in the Player's Handbook.

Open up Volo's Guide to Monsters, and you'll find darkvision among aasimar and tabaxi, among all the monstrous races available for player characters - bugbears, goblins, hobgoblins, kobolds, orcs, and yuan-ti - along with a few more who don't, like goliaths and tritons.

Because almost every species has darkvision, it doesn't end up having much effect in play. Being able to see in the dark doesn't make you feel special, and can't become a key facet of your character's personality, if everyone else can do the same. Likewise, darvision never offers a character the chance to reveal hidden information none of their party members can discover if everyone knows that information by default.

So it would be more interesting, I think, from the standpoint of both characterization and information gathering, if different characters had a variety of different abilities, instead of all having the same one. It makes sense that Underdark natives - drow, duergar, svirfneblin - might have true darkvision, but this ability will feel more special if they're the only ones. I would also for sure let them see right through magical darkness.

I've made a list of some possible replacements. I've assigned them based on species, but you could also roll the dice, or just pick one you like. After the list, I have some thoughts about what it means for 5e to be designed so that so many player characters end up with darkvision. You could also add any of these abilities to a magic lantern or to a pair of glasses, like Luna Lovegood's spectra-specs. You can't really do that with darkvision, since every lantern already grants the ability to see in the dark. (Although I do deeply love The Manse's idea - orcs can see in the dark because their eyes glow red, and you can make a lantern by filling a glass jar with orc eyes.)

If you add to the list, make sure not to include things like "knows true north" or "can accurately guess distances" or "can count all the coins in a hoard on sight". Those might be superpowers in real life, but most GMs regularly assume that all player characters can do all of those things; it's ingrained in the way we share information with players. Offering those as special abilities is either going to be a cheat to those players when everyone else gets the same information anyway, or its going to impoverish your game by removing several common ways of communicating about the game world.

The senses listed below could be "always on" or they could require concentration to use. Some of these senses more-or-less replicate the effect of a spell. If that bothers you, you could make it take as long as a ritual to use effectively. You could also rule that some of these senses only work in total darkness, giving the players and incentive to douse the lights. If you don't like any of these options, you could also remove darkvision and replace it with a language, or with another proficiency.

Hill Dwarves - Gold Sense
Some hill dwarves possess a "gold scent" - they can literally smell the presence of gold, and the greater the concentration, the stronger the smell. They can tell when they're in the immediate presence of gold, and are drawn to the largest supply in the area - unless that's already on their person! (This one is adapted from DCC.)

Others possess a "gold sight" that lets them see gold glowing with a warm yellow light. A single gold coin gives off less light than a candle, but a small cache will shine like a torch, and a hoard like the noonday sun.

Mountain Dwarves - Trap Sense
Raised in labyrinthine halls amidst every available architectural trick and travail, mountain dwarves have an innate sense for building features intended to deceive or deal harm. In any built environment, they'll notice when they're in the presence of a "trick" or "trap" although they won't automatically be able to identify the nature of the hazard.
(Yes, "find traps" is a 2nd level spell. So is "darkvision".)

Duergar - See Invisible
The diabolical duergar have mastered the magical art of turning invisible at will. With proprietary alchemical paints, they've also filled their cities and lairs with invisible hazards to ensnare invaders. What is invisible to outside eyes is not simply visible to the duergar, it actually glows with ghostly white light to their eyes.
(This could be in addition to their darkvision, instead of replacing it.)

High Elf - Aura Sight
Millennia of schooling and study have trained high elves to recognize magic on sight. Every living spellcaster possesses a faint aura, as does every magic item, and every creature with a magical attack. Depending on the circumstances and the strength of the magic, these auras may be faint, sometimes almost invisible. Powerful auras glow like a bonfire of magical potency.

Wood Elf - Door Sight
In ages past, every forest was filled with hidden doorways that led directly to the Feywild. Today, nearly all of those doors are gone, but wood elves retain a special sense for noticing the presence of secret passages. Doors that are hidden or locked by magic appear as glowing rectangles. Other doors might not be visible, although the elves will know they're there. The means to open these doors will not usually be obvious.

Drow - Poison Scent
Surrounded by scorpions and spiders, successive generations of their leaders assassinated by tainted food, adulterated drink, and poisoned blades, the drow have evolved an infallible nose for toxins of all kinds. They know when rations are unsafe, when monsters are venomous, and when weapons have been coated with poison. Drow with particularly discriminating palates can even identify different types of poison by scent alone, although such sommeliers require additional training in alchemy or herbalism.
(This is in addition to darkvision, however, drow just get regular old darkvision, not the superior kind.)

Stout Halfling - Food Sense
These hereditary gourmets have a knack for finding edible morsels. When foraging or examining the corpse of a monster, they're able to the safest and tastiest portions. Except in unusual situations, poisonous  items that offer no nourishment will appear obviously inedible. Stout halflings can also "follow their noses" to locate kitchens, larders, pantries, feast-halls, and even occasionally guardposts where meals are taken or prepared.
(This replaces Halfling Nimbleness, which becomes a Lightfoot ability only.)

Forest Gnome - Hazard Sense
The untamed wilderness is full of natural perils, and territories controlled by other species are more dangerous still, littered with abandoned siege weapons, crumbling border fortifications, and half-forgotten anti-invasion ordinance. Forest gnomes, who claim no territory and wander freely across the frontier and the settled lands, have encountered all of them. From infancy they learn the tell-tale signs of danger, and as long as they're outside, they know when a trap or natural hazard is present, although its source might not be readily apparent.

Rock Gnome - Machine Canny
Even rock gnomes who don't build machines themselves understand how they work, an ability that appears near-miraculous to other species. To gnomish eyes, every machine is made of parts that operate by cause and effect. "Cause" one part to activate, and its "effect" becomes the cause for the next part, and so on until the machine completes its final effect. While they have no special talent for spotting mechanisms, a rock gnome who notices a machine part can intuit its "cause" and its "effect" and can guess what kind of part comes before it and after it. They can also tell if the part is broken, or if its link in the chain of cause and effect is broken.

Deep Gnome - Gem Sight
Although everyone perceives gemstones as lustrous, to deep gnome eyes they literally glow, the color of the light determine by the color of the gem. Raw and uncut stones give off a dim light that aids in mining, while finished jewels cast a brilliant sparkle. Though unlit to outside eyes, deep gnome cities and lairs appear filled with rainbows and kaleidoscopes to their builders, with strategically placed gems drenching every corner in colorful light.
(This could replace darkvision, leaving svirfneblin on equal footing with others outside their own territory.)

Half Elf - Fey Sense
The elfin blood in half-elves veins calls out to other fey, granting them a powerful intuition that is felt more than seen. Half elves can identify fey creatures, and can tell the difference between those native to the Feywild and those born into the material world. They can identify radiant magic and positive energy. They can identify fairy pranks, even before the prankster has been spotted. They can see the bond between warlocks and the Archfey and the Celestial; and they can tell when someone has been charmed, frightened, or possessed by a fairy or celestial.

Half Orc - Shadow Sight
Born between worlds, half-orcs can see just past the veil between worlds, into the Border Ethereal and the Shadowfell. They can perceive ghosts and fiends lurking invisible and incorporeal, whenever they are close enough to manifest. They can see the difference between dead bodies and the undead, between ordinary shadows and shadow-monsters. Half orcs can see the bond that connects warlocks to the Raven Queen or the Fiend; can perceive when someone has been charmed, frightened, or possessed by an undead creature or fiend; and can see necrotic magic and negative energy whenever they're used.

Tiefling - Mind Reading
If a tiefling can look directly at another being and concentrate, they can actually hear the other's thoughts, the voice in their head like a half-whispered, half-mumbled monologue. This only works if the tiefling can see the others' eyes, the windows to their soul. They hear surface thoughts only, and can't elicit or insert specific ideas, but their infernal ears are especially attuned to thoughts of temptation and desire.
(Like "darkvision" and "find traps", "detect thoughts" is also a 2nd level spell.)

Other Options
When designing a new 5e race that you're tempted to give darkvision, ask yourself if any other divination ability might be more thematically appropriate. Does your species have infravision, able to see heat signatures, but unable to detect oozes, constructs, undead, or even lizards, fish, or amphibians against the ambient air temperature? Can they dowse for water? Are they magnetically drawn to the presence of iron? Can they see emotions? Can they hear lies? Are they able to perceive cosmic alignment, or see the umbilical threads that bonds believers to their deities? Can they sometimes talk to insects or plants or rocks? Can they speak with the recently dead? Be creative, and your world, and your players' experiences, will be richer for it.

So, maybe almost every species has darkvision. So what? Is that a problem? Well, maybe. I can think of two possible reasons for 5e to be designed this way, although of course I'm only speculating. The first possibility is that darkvision isn't really intended to be relevant in play very often or to have a frequent mechanical effect. Maybe it's mostly meant to be a nifty factoid about your character, something flavorful to distinguish the various demihumans from humanity, but ultimately no more important than green skin or pointed ears. (Although if so, it ultimately makes humans seem like the strange ones, cursed with a night-blindness that doesn't afflict anyone else. And at least "I have green skin" and "I have pointy ears" mark actual differences between half-orcs and half-elves!)

The second possibility is that WOTC is scared to death of resource management play, and doing everything in their power to prevent it. Maybe they think that only asshole GMs run resource management games, and want those assholes to stay away from their popular new edition. Maybe they're afraid that a novice GM will find an asshole OSR blog exhorting that "Gary wants you to count torches", will naively try to run a resource management game, and will end up driving themselves and their novice player friends right on back out of the hobby after a single bad session.

Whatever the reason, one thing is clear. Between the ubiquity of darkvision and making the "light" spell a cantrip with unlimited re-use, it's basically impossible to run a game where the player characters get trapped somewhere because they're unable to see.

Now, I've been very vocal in the past about not wanting to run a darkcrawl game, but I also don't really care for solutions like this. They feel dishonest. If you don't want to play a game where it's possible to get trapped in the dark, then don't, but don't pretend to offer it as a possibility with one hand, while using the other hand to smuggle it back off the table. Don't make a rule, then give every player permission to break it. Don't claim darkness is important, then fail to write any procedures that would actually support using it, then try to escape the contradiction you've set up by handing out "get out of dark free" cards.

Be honest. Tell potential GMs "The rules of this game assume that a low level of lighting is available at all time. Whether from moon and starlight outside, phosphorescent fungus growing in caverns and tombs, intelligent monsters lighting candles and braziers to illuminate dungeons for their own purposes, or from the player characters bearing torches and lanterns - it will never be truly dark. If your fictional solution involves the characters wielding light sources, these should never cost treasure to supply, never run out, and never count against the characters' encumbrance limits. Assume they are omnipresent, like the clothes on the characters' backs. This is not a game about counting torches or mapping caves in the dark." Then set the example and teach novice GMs how to do this by using the read-alouds and box-text in your sample adventures.

That would have pretty much the same effect as the current arrangement, but it would have the benefit of not pretending to do something you really don't, and it would allow GMs and players who want to engage in resource management play to do so without having to rewrite the spell list and nearly every species' racial traits. Ironically, under such an arrangement, the rules themselves would be more agnostic toward RM play than they are now, when they claim to take no official stand, but then saturate the game world with so much darkvision and magical light that RM play is rendered impossible in practice.


  1. Sensible ideas. I’d also limit the ‘special’ races available in any campaign I ran. A bit like the idea of the Ten Monster Setting - a more limited set of races and monsters etc helps give each setting or campaign its own distinct feel. So does differentiating the ‘special senses’ as you’re suggesting. Less is more, as they say, unless one of your goals *is* to have an overwhelming variety as part of the setting’s feel.

    1. It makes a certain kind of sense for D&D and Pathfinder to try to include every possible option. They are the official, canonical rules, and if they don't include it, some people won't allow it at their table.

      As you say though, many home games, even ones playing entirely "by the book", would benefit from using a more limited subset. I mean, in practice, you HAVE to use a limited set anyway, but what I mean is, from intentionally restricting the options at the outset of a campaign. Which doesn't have to be the GM's responsibility alone. It can be a collaborative worldbuilding exercise.

      For example, in my Barrowmaze / In the Shadow of Mount Rotten campaign, I had Dwarven Delvers and Dwarven Machinists, and Elven Courtiers and Enchanters, instead of their more usual versions. I also added the human Venturer mercantilist class. It kind of changed the mood of things in a way that I liked.

  2. These are all great, more interesting alternatives to dark vision. I feel like there's a lot of room for interesting abilities if we play more with the 5 senses. Echolocation is just dark vision for your ears basically.

    1. I mostly worked with vision and smell (well, and "spider sense" sort of) but you're right, there's a lot of room for other abilities.

      I just feel like, since 5e already decided that virtually every race gets a divination ability, more variety would be nice. You could do something like this with a handful of GLOG races, if you were so inclined.

  3. I think that darkvision is a bad ability and I don't include it in my games--these are, by and large, refreshing alternatives.

    There are two main reasons I dislike darkvision.
    1) It's passive. Passive abilities are often forgotten about by both the player and the GM (especially if I'm GMing - I got enough to think about). When it's brought it up, it's often breaks the flow of the narrative. "Oh, wait, no, duh, you can see it Legolas. You wouldn't have been surprised by the Bugbear. Uhhh. Sorry."
    2) Information disparity. If 1 person in the party has (and remembers to use) darkvision, essentially everybody in the party does. "OK, I might not be able to see the bugbear in the darkness, but I can tell that Legolas is firing arrows at something and so I'm going to get closer until it's in the range of my torch." Or worse, only some players gets to interact with the environment while the humans and halflings have to sit around blind and unhappy.

    The ideas that are more active in your list especially delight me, especially the halfling's "sniff out food" ability.

    1. Oh wait I forgot another reason I hate it!

      3) Removes dungeoneering. Dungeons should stay scary. Darkness is one of the main vectors. Carrying candles and torches is a genre staple that should stay at every level. Introducing spells and abilities that overcome the basic dangers of the dungeon remove one half of the name of the game, and then it's just "Dragons," which is not as fun.

    2. The halfling one is my personal favorite, and it might be interesting to try thinking of other abilities that are more like it. Maybe some dwarves can "smell iron" which leads them to any kind of blacksmithing room or armory. Maybe some really literary race is drawn to the library.

      Anyway yes, all three of your points are really cogent. Active abilities are more interesting than passive ones (which are also easy to forget), they invite a kind of kludgy metagaming where everyone who doesn't have darkvision has to pretend they can't hear certain descriptions, and yeah, it removes an element of dungeoneering that some people want, in a way that's not necessarily so easy to put back.

      (Actually, is that last statement true? I mean, yes, the GM has to get their players to agree to give up darkvision, cantrip light, and permanent light ... but the GM ought to be getting their players to agree that they want to play a darkcrawl game in the first place. So is that extra step actually a burden?)

  4. Two thoughts.
    A) Those are great replacements for darkvision - I especially like that they are almost all non-combat abilities. Giving PCs different odd, highly situational abilities encourages their use and through them schemes and plans beyond "move to next encounter and engage in tactical combat or skill challenge".

    B)You offer a good reminder that there are extraordinary abilities of perception accorded to PCs without mechanics or being noted in the rules at all (coin hoard counting etc.) and it's useful to remember that antagonistic isn't just suddenly providing bad choices or concealing information, but also changing norms or expectations without notice.

    1. I guess being able to see and hear during combat is important, but I mostly think of PC senses as applying to the task of exploration. Which I guess is why I wrote them the way I did. I'm glad you like that aspect though.

      To your second point, right, if your goal as a GM is to not be your players's adversary (a good goal!) then it's always going to be useful to think about what they expect and try not to violate those expectations without warning them first, and maybe getting them to explicitly agree to them. For example, if you're going to take away the "compass sense" that most PCs get by default, that shouldn't be a surprise you spring on them.

  5. Yep, darkvision is annoying, and I've never been a huge fan of "infravision" either (seemed too sci-fi to me.) Your thoughts are spot-on, with creative alternatives.

    1. Thermal vision is pretty sci-fi, isn't it? I'm glad you liked some of my ideas!

  6. Wow, very cool and evocative. Thank you!

  7. Excellent points about the ubiquity of nightvision and light cantrips. Even if you take away Darkvision, very few parties will ever end up running out of light (maybe it's just because I often have kids at my table, but I feel like I spend half an hour every session listening to debates about exactly what gets the light cantrip cast on it. Kids love the light cantrip so much).

    The best thing about these alternatives is the way they further differentiate the races. It makes your dwarves dwarvier and your halflings halflingier. I especially like that the half-races get their own, liminally-themed senses.

    It does take a little extra prep on the GM's part, however. You have to make extra notes of where the gold and the larders are, now that your players can sense them when you're still several pages from that room's description.

    1. I was just thinking that I needed to go consider what special senses to apply to my homebrew races, which then made me think "what should a human's special sense be?" Which then reminded me that I drew a comic, years ago, for, I think, Opium Magazine, that posited that Earth was the only planet where a sense of smell evolved. Real highbrow speculative fiction followed, I assure you.

    2. Pulpatooner, I have no doubt that Opium Magazine is perpetually highbrow!

      I appreciate you sharing about your experience GMing for kids. Who knew they'd be so interested in casting light spells!

      It's always interesting to ask, what if humans aren't "standard", what should they be like if they aren't the presumed "norm" that everyone else is a variation on?

      I don't have a good answer for senses, although in general, my thinking is that we're more social than other species. We live in full-on cities that are crowded and full of strangers, whereas every other fantasy folk resides in small traditional villages where everyone knows everyone, or else they live in families or clans or are hermits. Humans are unique in their sociability.

      Instead of getting open-ended ability score boosts and extra skills or feats, humans could get a Charisma boost, an extra contact (if your game has those), or could start out with a hireling.

      (Also, thank you for noticing the half-elf and half-orc senses!)

    3. In real life, humans are one of the few mammals with color vision.

  8. Echoes my dislike for darkvision for removing part of the resource management aspect of crawling and does a much more interesting thing than my removing infra/darkvision for PCs from my BX game.

    1. The mountain dwarf and wood elf abilities are actually meant to kind of mimic their B/X talents. I'd love to hear about how it goes with the halfling "Toucan Sam" ability though!

  9. I love that your suggestion nearly solves both the problem of darkvision and the rulebooks being full of random divination spell effects that no one in their right mind would want, need, or prepare.


    1. Ha, yes, that's a good point. Several of these are more appealing as minor character abilities than they are as dedicated spells.

  10. I love that list! I very much dislike darkvision (and the light cantrip as well); these are much more evocative and fantastical in nature (in the sort of whimsical way I've grown - yet again - very fond of lately).

    Also, thanks for pointing me toward All Dead Generations; I completely missed those posts.

  11. I have a species in one of my settings with an "earth sense"- they can pick up on things like the presence of a cave beneath their feet, or whether or not a nearby volcano is about to erupt.
