In situations where keeping track of the passage of time is important, the GM determines the time a task requires. The GM might use a different time scale depending on the context of the situation at hand. In a dungeon environment, the adventurers’ movement happens on a scale of minutes. It takes them about a minute to creep down a long hallway, another minute to check for traps on the door at the end of the hall, and a good ten minutes to search the chamber beyond for anything interesting or valuable.
In a city or wilderness, a scale of hours is often more appropriate. Adventurers eager to reach the lonely tower at the heart of the forest hurry across those fifteen miles in just under four hours’ time.
For long journeys, a scale of days works best. Following the road from Baldur’s Gate to Waterdeep, the adventurers spend four uneventful days before a goblin ambush interrupts their journey.
In combat and other fast-‐‑paced situations, the game relies on rounds, a 6-‐‑second span of time.
Swimming across a rushing river, sneaking down a dungeon corridor, scaling a treacherous mountain slope—all sorts of movement play a key role in fantasy gaming adventures.
The GM can summarize the adventurers’ movement without calculating exact distances or travel times: “You travel through the forest and find the dungeon entrance late in the evening of the third day.” Even in a dungeon, particularly a large dungeon or a cave network, the GM can summarize movement between encounters: “After killing the guardian at the entrance to the ancient dwarven stronghold, you consult your map, which leads you through miles of echoing corridors to a chasm bridged by a narrow stone arch.”
Sometimes it’s important, though, to know how long it takes to get from one spot to another, whether the answer is in days, hours, or minutes. The rules for determining travel time depend on two factors: the speed and travel pace of the creatures moving and the terrain they’re moving over.
Every character and monster has a speed, which is the distance in feet that the character or monster can walk in 1 round. This number assumes short bursts of energetic movement in the midst of a life-‐‑ threatening situation.
The following rules determine how far a character or monster can move in a minute, an hour, or a day.
While traveling, a group of adventurers can move at a normal, fast, or slow pace, as shown on the Travel Pace table. The table states how far the party can move in a period of time and whether the pace has any effect. A fast pace makes characters less perceptive, while a slow pace makes it possible to sneak around and to search an area more carefully.
Forced March. The Travel Pace table assumes that characters travel for 8 hours in day. They can push on beyond that limit, at the risk of exhaustion.
For each additional hour of travel beyond 8 hours, the characters cover the distance shown in the Hour column for their pace, and each character must make a Constitution saving throw at the end of the hour.
The DC is 10 + 1 for each hour past 8 hours. On failed saving throw, a character suffers one level of exhaustion (see appendix PH-‐‑A).
Mounts and Vehicles. For short spans of time (up to an hour), many animals move much faster than humanoids. A mounted character can ride at a gallop for about an hour, covering twice the usual distance for a fast pace. If fresh mounts are available every 8 to 10 miles, characters can cover larger distances at this pace, but this is very rare except in densely populated areas.
Characters in wagons, carriages, or other land vehicles choose a pace as normal. Characters in a waterborne vessel are limited to the speed of the vessel, and they don’t suffer penalties for a fast pace or gain benefits from a slow pace. Depending on the vessel and the size of the crew, ships might be able to travel for up to 24 hours per day.
Certain special mounts, such as a pegasus or griffon, or special vehicles, such as a carpet of flying, allow you to travel more swiftly.
The travel speeds given in the Travel Pace table assume relatively simple terrain: roads, open plains, or clear dungeon corridors. But adventurers often face dense forests, deep swamps, rubble-‐‑filled ruins, steep mountains, and ice-‐‑covered ground—all considered difficult terrain.
You move at half speed in difficult terrain— moving 1 foot in difficult terrain costs 2 feet of speed—so you can cover only half the normal distance in a minute, an hour, or a day.
Movement through dangerous dungeons or wilderness areas often involves more than simply walking. Adventurers might have to climb, crawl, swim, or jump to get where they need to go.
While climbing or swimming, each foot of movement costs 1 extra foot (2 extra feet in difficult terrain), unless a creature has a climbing or swimming speed. At the GM’s option, climbing a slippery vertical surface or one with few handholds requires a successful Strength (Athletics) check. Similarly, gaining any distance in rough water might require a successful Strength (Athletics) check.
Your Strength determines how far you can jump. Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump. When you make a standing long jump, you can leap only half that distance. Either way, each foot you clear on the jump costs a foot of movement.
This rule assumes that the height of your jump doesn’t matter, such as a jump across a stream or chasm. At your GM’s option, you must succeed on a DC 10 Strength (Athletics) check to clear a low obstacle (no taller than a quarter of the jump’s distance), such as a hedge or low wall. Otherwise, you hit it.
When you land in difficult terrain, you must succeed on a DC 10 Dexterity (Acrobatics) check to land on your feet. Otherwise, you land prone.
High Jump. When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier if you move at least 10 feet on foot immediately before the jump. When you make a standing high jump, you can jump only half that distance. Either way, each foot you clear on the jump costs a foot of movement. In some circumstances, your GM might allow you to make a Strength (Athletics) check to jump higher than you normally can.
You can extend your arms half your height above yourself during the jump. Thus, you can reach above you a distance equal to the height of the jump plus 11⁄2 times your height.
By its nature, adventuring involves delving into places that are dark, dangerous, and full of mysteries to be explored. The rules in this section cover some of the most important ways in which adventurers interact with the environment in such places.
A fall from a great height is one of the most common hazards facing an adventurer. At the end of a fall, a creature takes 1d6 bludgeoning damage for every 10 feet it fell, to a maximum of 20d6. The creature lands prone, unless it avoids taking damage from the fall.
A creature can hold its breath for a number of minutes equal to 1 + its Constitution modifier (minimum of 30 seconds).
When a creature runs out of breath or is choking, it can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round). At the start of its next turn, it drops to 0 hit points and is dying, and it can’t regain hit points or be stabilized until it can breathe again.
For example, a creature with a Constitution of 14 can hold its breath for 3 minutes. If it starts suffocating, it has 2 rounds to reach air before it drops to 0 hit points.
The most fundamental tasks of adventuring— noticing danger, finding hidden objects, hitting an enemy in combat, and targeting a spell, to name just a few—rely heavily on a character’s ability to see. Darkness and other effects that obscure vision can prove a significant hindrance.
A given area might be lightly or heavily obscured. In a lightly obscured area, such as dim light, patchy fog, or moderate foliage, creatures have disadvantage on Wisdom (Perception) checks that rely on sight.
A heavily obscured area—such as darkness, opaque fog, or dense foliage—blocks vision entirely. A creature effectively suffers from the blinded condition (see appendix PH-‐‑A) when trying to see something in that area.
The presence or absence of light in an environment creates three categories of illumination: bright light, dim light, and darkness.
Bright light lets most creatures see normally. Even gloomy days provide bright light, as do torches, lanterns, fires, and other sources of illumination within a specific radius.
Dim light, also called shadows, creates a lightly obscured area. An area of dim light is usually a boundary between a source of bright light, such as a torch, and surrounding darkness. The soft light of twilight and dawn also counts as dim light. A particularly brilliant full moon might bathe the land in dim light.
Darkness creates a heavily obscured area. Characters face darkness outdoors at night (even most moonlit nights), within the confines of an unlit dungeon or a subterranean vault, or in an area of magical darkness.
A creature with blindsight can perceive its surroundings without relying on sight, within a specific radius. Creatures without eyes, such as oozes, and creatures with echolocation or heightened senses, such as bats and true dragons, have this sense.
Many creatures in fantasy gaming worlds, especially those that dwell underground, have darkvision. Within a specified range, a creature with darkvision can see in darkness as if the darkness were dim light, so areas of darkness are only lightly obscured as far as that creature is concerned. However, the creature can’t discern color in darkness, only shades of gray.
A creature with truesight can, out to a specific range, see in normal and magical darkness, see invisible creatures and objects, automatically detect visual illusions and succeed on saving throws against them, and perceives the original form of a shapechanger or a creature that is transformed by magic. Furthermore, the creature can see into the Ethereal Plane.
Characters who don’t eat or drink suffer the effects of exhaustion (see appendix PH-‐‑A). Exhaustion caused by lack of food or water can’t be removed until the character eats and drinks the full required amount.
A character needs one pound of food per day and can make food last longer by subsisting on half rations.
Eating half a pound of food in a day counts as half a day without food.
A character can go without food for a number of days equal to 3 + his or her Constitution modifier (minimum 1). At the end of each day beyond that limit, a character automatically suffers one level of exhaustion.
A normal day of eating resets the count of days without food to zero.
A character needs one gallon of water per day, or two gallons per day if the weather is hot. A character who drinks only half that much water must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion at the end of the day. A character with access to even less water automatically suffers one level of exhaustion at the end of the day.
If the character already has one or more levels of exhaustion, the character takes two levels in either case.
A character’s interaction with objects in an environment is often simple to resolve in the game. The player tells the GM that his or her character is doing something, such as moving a lever, and the GM describes what, if anything, happens.
For example, a character might decide to pull a lever, which might, in turn, raise a portcullis, cause a room to flood with water, or open a secret door in a nearby wall. If the lever is rusted in position, though, a character might need to force it. In such a situation, the GM might call for a Strength check to see whether the character can wrench the lever into place. The GM sets the DC for any such check based on the difficulty of the task.
Characters can also damage objects with their weapons and spells. Objects are immune to poison and psychic damage, but otherwise they can be affected by physical and magical attacks much like creatures can. The GM determines an object’s Armor Class and hit points, and might decide that certain objects have resistance or immunity to certain kinds of attacks. (It’s hard to cut a rope with a club, for example.) Objects always fail Strength and Dexterity saving throws, and they are immune to effects that require other saves. When an object drops to 0 hit points, it breaks.
A character can also attempt a Strength check to break an object. The GM sets the DC for any such check.
Heroic though they might be, adventurers can’t spend every hour of the day in the thick of exploration, social interaction, and combat. They need rest—time to sleep and eat, tend their wounds, refresh their minds and spirits for spellcasting, and brace themselves for further adventure.
Adventurers can take short rests in the midst of an adventuring day and a long rest to end the day.
A short rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.
A character can spend one or more Hit Dice at the end of a short rest, up to the character’s maximum number of Hit Dice, which is equal to the character’s level. For each Hit Die spent in this way, the player rolls the die and adds the character’s Constitution modifier to it. The character regains hit points equal to the total. The player can decide to spend an additional Hit Die after each roll. A character regains some spent Hit Dice upon finishing a long rest, as explained below.
A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours. If the rest is interrupted by a period of strenuous activity—at least 1 hour of walking, fighting, casting spells, or similar adventuring activity—the characters must begin the rest again to gain any benefit from it.
At the end of a long rest, a character regains all lost hit points. The character also regains spent Hit Dice, up to a number of dice equal to half of the character’s total number of them (minimum of one die). For example, if a character has eight Hit Dice, he or she can regain four spent Hit Dice upon finishing a long rest.
A character can’t benefit from more than one long rest in a 24-‐‑hour period, and a character must have at least 1 hit point at the start of the rest to gain its benefits.
Between trips to dungeons and battles against ancient evils, adventurers need time to rest, recuperate, and prepare for their next adventure. Many adventurers also use this time to perform other tasks, such as crafting arms and armor, performing research, or spending their hard-‐‑earned gold.
In some cases, the passage of time is something that occurs with little fanfare or description. When starting a new adventure, the GM might simply declare that a certain amount of time has passed and allow you to describe in general terms what your character has been doing. At other times, the GM might want to keep track of just how much time is passing as events beyond your perception stay in motion.
Between adventures, you choose a particular quality of life and pay the cost of maintaining that lifestyle.
Living a particular lifestyle doesn’t have a huge effect on your character, but your lifestyle can affect the way other individuals and groups react to you. For example, when you lead an aristocratic lifestyle, it might be easier for you to influence the nobles of the city than if you live in poverty.
Between adventures, the GM might ask you what your character is doing during his or her downtime. Periods of downtime can vary in duration, but each downtime activity requires a certain number of days to complete before you gain any benefit, and at least 8 hours of each day must be spent on the downtime activity for the day to count. The days do not need to be consecutive. If you have more than the minimum amount of days to spend, you can keep doing the same thing for a longer period of time, or switch to a new downtime activity.
Downtime activities other than the ones presented below are possible. If you want your character to spend his or her downtime performing an activity not covered here, discuss it with your GM.
You can craft nonmagical objects, including adventuring equipment and works of art. You must be proficient with tools related to the object you are trying to create (typically artisan’s tools). You might also need access to special materials or locations necessary to create it. For example, someone proficient with smith’s tools needs a forge in order to craft a sword or suit of armor.
For every day of downtime you spend crafting, you can craft one or more items with a total market value not exceeding 5 gp, and you must expend raw materials worth half the total market value. If something you want to craft has a market value greater than 5 gp, you make progress every day in 5-‐‑ gp increments until you reach the market value of the item. For example, a suit of plate armor (market value 1,500 gp) takes 300 days to craft by yourself.
Multiple characters can combine their efforts toward the crafting of a single item, provided that the characters all have proficiency with the requisite tools and are working together in the same place. Each character contributes 5 gp worth of effort for every day spent helping to craft the item. For example, three characters with the requisite tool proficiency and the proper facilities can craft a suit of plate armor in 100 days, at a total cost of 750 gp.
While crafting, you can maintain a modest lifestyle without having to pay 1 gp per day, or a comfortable lifestyle at half the normal cost.
You can work between adventures, allowing you to maintain a modest lifestyle without having to pay 1 gp per day. This benefit lasts as long you continue to practice your profession.
If you are a member of an organization that can provide gainful employment, such as a temple or a thieves’ guild, you earn enough to support a comfortable lifestyle instead.
If you have proficiency in the Performance skill and put your performance skill to use during your downtime, you earn enough to support a wealthy lifestyle instead.
You can use downtime between adventures to recover from a debilitating injury, disease, or poison.
After three days of downtime spent recuperating, you can make a DC 15 Constitution saving throw. On a successful save, you can choose one of the following results:
The time between adventures is a great chance to perform research, gaining insight into mysteries that have unfurled over the course of the campaign. Research can include poring over dusty tomes and crumbling scrolls in a library or buying drinks for the locals to pry rumors and gossip from their lips.
When you begin your research, the GM determines whether the information is available, how many days of downtime it will take to find it, and whether there are any restrictions on your research (such as needing to seek out a specific individual, tome, or location). The GM might also require you to make one or more ability checks, such as an Intelligence (Investigation) check to find clues pointing toward the information you seek, or a Charisma (Persuasion) check to secure someone’s aid. Once those conditions are met, you learn the information if it is available.
For each day of research, you must spend 1 gp to cover your expenses. This cost is in addition to your normal lifestyle expenses.
You can spend time between adventures learning a new language or training with a set of tools. Your GM might allow additional training options.
First, you must find an instructor willing to teach you. The GM determines how long it takes, and whether one or more ability checks are required.
The training lasts for 250 days and costs 1 gp per day. After you spend the requisite amount of time and money, you learn the new language or gain proficiency with the new tool.
