Notes
- If a creature becomes Prone at the start of its turn, it uses half its available movement to stand up. If a creature is knocked prone during its turn, its turn automatically ends.
- Knocking a creature Prone and reducing its movement speed below 50% does not automatically skip its next turn because creatures use 50% of their available movement to stand up.
- Some creatures are immune to the Prone condition, including those without a physical body (such as Shadows and Wraiths).
causes a target to suffer from Hideous Laughter, which has the effect of Prone, but is not technically considered as such.- Becoming prone instantly ends Concentration.
Sources of Prone[edit | edit source]
Indefinite duration[edit | edit source]
The following sources of Prone inflict the condition indefinitely. It can still be removed if the affected creature spends movement speed to get up. However, if the creature is unable to move (for example with 
, 
, 
, 
, 
, and 
), it remains prone indefinitely.
Two turn duration[edit | edit source]
Two turns is the typical duration for a Prone effect. Since the duration of Prone ticks down at the start of the affected creature's turn, a 2 turn duration is effectively 1 round. The exact behaviour is as follows:
- At the start of the affected creature's turn, the remaining duration ticks down to 1 turn.
- If the affected creature can spend movement speed, it does so and stands up.
- If it cannot, it remains prone and skips its turn. In this case, at the start of the following turn, the Prone duration expires and the creature stands up with no expenditure of movement.
- If Prone was caused by certain sources, such as
, 
, 
, or 
, duration 1 cannot be be increased to 2 before the condition has ended, which usually means not until the next turn. For some other sources, such as 
Ice, a separate Prone condition with duration 2 can be applied.
The following sources have a duration of 2 turns:
One turn duration[edit | edit source]
The following sources of Prone only inflict it for 1 turn. Since the duration of Prone ticks down at the start of an affected creature's turn, the condition ends before it has to expend movement speed to get up. As a result, these sources of Prone are significantly less effective than others.
