Dungeons and Dragons players often wonder about the consequences of their characters going without sleep. While the Basic Rules and Player's Handbook (PHB) are vague on this topic, Xanathar's Guide to Everything provides optional rules for Going without a Long Rest. These rules introduce a mechanic where characters must make a Constitution saving throw at the end of a 24-hour period without a long rest, gaining a level of exhaustion on a failed throw. The DC for this saving throw starts at 10 and increases by 5 for each additional 24 hours without rest. While these rules are not mandatory, they provide a way to simulate the effects of sleep deprivation and exhaustion on characters, adding an extra layer of challenge and realism to the game.

| Consequences | Going without sleep does have its consequences |
| Constitution saving throw | DC 10 |

What You'll Learn
A long rest is not mandatory, but sleep deprivation has consequences
While a long rest is not compulsory in the game, sleep deprivation can have negative consequences for characters and creatures. The rules outlined in Xanathar's Guide to Everything are optional and can be used to account for the effects of sleep deprivation.
According to the rules, whenever a character goes 24 hours without a long rest, they must make a DC 10 Constitution saving throw or suffer one level of exhaustion. The DC increases by 5 for each additional 24-hour period without rest. This means that a character can go 48 hours without sleep, but beyond that, the chances of avoiding exhaustion become slim.
The levels of exhaustion in the game have detrimental effects, which stack as a character progresses through them. Some of the ways to remove exhaustion include sleeping, using a potion of vitality, or being raised from the dead with a spell or magic item.
It is worth noting that certain character features, such as the aspect of the moon warlock invocation and the undying nature Undying warlock feature, allow characters to forgo sleep. Additionally, the Sand Survivor ranger subclass gains immunity to exhaustion at level 15, making them impervious to the effects of sleep deprivation.
While the rules in Xanathar's Guide provide a framework for handling sleep deprivation, Dungeon Masters (DMs) have the discretion to use or discard them as they see fit, allowing for flexibility in how exhaustion is handled in the game.

DC 10 Constitution saving throw or suffer one level of exhaustion
In Dungeons & Dragons, a long rest is never mandatory, but going without sleep does have its consequences. If you want to account for the effects of sleep deprivation on characters and creatures, you can use the rules in Xanathar's Guide to Everything.
According to Xanathar's Guide, whenever a character ends a 24-hour period without finishing a long rest, they must make a DC 10 Constitution saving throw or suffer one level of exhaustion. The DC increases by 5 for each additional 24 hours the character stays awake, and it resets to 10 when they finish a long rest. This means that the longer a character goes without sleep, the harder it becomes to fight off exhaustion.
The rules for exhaustion in Xanathar's Guide are optional, and Dungeon Masters (DMs) may choose to use or discard them as they see fit. Additionally, there are other ways to manage exhaustion in the game. For example, the potion of vitality can remove any levels of exhaustion currently being suffered, and being raised from the dead can also remove one level of exhaustion. Certain character features, such as the Sand Survivor ranger subclass or the Warforged race, grant immunity to exhaustion.
It's worth noting that the Basic Rules and the Player's Handbook (PHB) do not provide specific consequences for going without sleep, other than not gaining the benefits of a long rest. However, the PHB does include rules for managing exhaustion, such as the need to finish a long rest with at least 6 hours of sleep and no more than 2 hours of light activity.

Exhaustion levels have detrimental effects that stack
While a long rest is never mandatory, going without sleep does have consequences. If you want to account for the effects of sleep deprivation on characters and creatures, you can use the rules provided in Xanathar's Guide to Everything.
According to the guide, whenever a character ends a 24-hour period without finishing a long rest, they must make a DC 10 Constitution saving throw or suffer one level of exhaustion. The DC increases by 5 for each additional 24 hours without sleep. This means that the detrimental effects of exhaustion will stack the longer a character goes without rest.
There are six levels of exhaustion, each with its own negative consequences. The specific effects of each level are not explicitly stated in the sources provided, but they likely include increased fatigue, reduced cognitive function, and impaired physical abilities. The character's ability to fight off exhaustion becomes increasingly difficult as they stay awake for multiple days.
It is important to note that there are ways to mitigate exhaustion. For example, the Potion of Vitality can remove any levels of exhaustion currently being suffered. Additionally, certain character subclasses or features, such as the Sand Survivor ranger subclass or the Warforged race, may grant immunity to exhaustion or reduce its effects.
The rules regarding exhaustion and sleep deprivation are optional and can be adjusted or disregarded at the Dungeon Master's discretion.

Potion of Vitality removes exhaustion levels
The Potion of Vitality is a very rare item in the world of Dungeons and Dragons. When consumed, it removes any exhaustion the drinker is suffering from, ending any levels of exhaustion they have. The potion also cures diseases and poisons, ending the poisoned condition. For the next 24 hours, the drinker regains the maximum number of hit points for any hit dice spent.
The potion is described as a crimson liquid, pulsing with a small amount of light, similar to a beating heart. It is also referred to as "magic coffee" by some players. The potion allows the drinker to feel more rested and healthy than normal after consuming it and resting.
The effects of the potion can be replicated by casting healing spells onto a honeystone. One of the possible ingredients for crafting this potion is coffee beans.
In terms of in-game value, the potion is considered very rare and powerful. Some players suggest that a potion curing all levels of exhaustion should be priced at the higher end of rare items (around 2500 gp), while a potion curing just one level of exhaustion would be cheaper (around 250 gp).
The rules regarding hit dice and long rests are flexible, and Dungeon Masters (DMs) can adjust them as they see fit for their campaigns. However, normally, a character can regain half of the total number of hit dice used in the previous short rest by taking a long rest.

Some character builds are immune to exhaustion
While it is uncommon, some character builds in D&D are immune to exhaustion. Exhaustion is a condition that imposes tiered detriments to a character's abilities, and it can even lead to death if not remedied by the sixth level. Usually, constructs, elementals, and some undead (but not vampires) are immune to the exhaustion condition.
For example, a sorcerer/warlock ghost character who is immune to exhaustion would not face any penalties for skipping long rests. They could simply take multiple short rests every night and accumulate an "infinite" number of spell slots. However, creating such a character without immunity to exhaustion is possible, but more challenging.
In addition, at 15th level, a character gains immunity to exhaustion, expanding on previous features that reduce their need to eat and drink. This includes immunity to starvation, dehydration, sleep deprivation, overheating, and freezing.
It is important to note that the Basic Rules and the Player's Handbook (PHB) do not specify the consequences of a character's prolonged lack of sleep, other than not gaining the benefits of a long rest. With the release of Xanathar's Guide to Everything, optional rules were introduced to address sleep deprivation. According to these rules, a long rest is never mandatory, but going without sleep can lead to levels of exhaustion that increase each day.
To avoid a level of exhaustion after 24 hours of being awake, a character must make a DC 10 Constitution saving throw, with the DC increasing by 5 for each additional 24-hour period without rest. However, it is worth mentioning that a character can go 48 hours without sleep by strategically timing their long rests.
