Some special abilities and environmental hazards, such as starvation and the long-term effects of freezing or scorching temperatures, can lead to a special condition called exhaustion. Exhaustion is measured in six levels. An effect can give a creature one or more levels of exhaustion, as specified in the effect's description.
| Level | Effect |
| 1 | Cannot Take the Dash Action |
| 2 | Disadvantage on Strength, Dexterity, and Constitution checks. |
| 3 | Speed halved and unable to maintain a fast travel pace |
| 4 | Disadvantage on attack rolls and saving throws using Strength, Dexterity, or Constitution, and unable to maintain a normal travel pace |
| 5 | Hit Dice halved |
| 6 | Speed reduced to 5 ft. and unable to maintain a slow travel pace |
| 7 | Doomed |
A creature that reaches the 7th level of Exhaustion and becomes Doomed is in imminent risk of dying. Unless some form of magical or medical aid that reduces the creature's level of Exhaustion by one step is administered within 1d12 hours, the creature dies.
If an already exhausted creature suffers another effect that causes exhaustion, its current level of exhaustion increases by the amount specified in the effect's description.
A creature suffers the effect of its current level of exhaustion as well as all lower levels. For example, a creature suffering level 2 exhaustion has its speed halved and has disadvantage on ability checks.
An effect that removes exhaustion reduces its level as specified in the effect's description, with all exhaustion effects ending if a creature's exhaustion level is reduced below 1.
Finishing a long rest reduces a creature's exhaustion level by 1, provided that the creature has also ingested some food and drink. Also, being raised from the dead reduces a creature’s exhaustion level by 1.
