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 - Disadvantage on Ability Checks
2 - Speed halved
3 - Disadvantage on Attack rolls and Saving Throws
4 - Hit point maximum halved
5 - Speed reduced to 0
6 - Death
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.
