Suffocating

The creature cannot breathe.

This condition is applied automatically when a creature cannot hold its breath anymore or is choking.
A creature can hold its breath for a number of minutes equal to 1 + its Constitution Modifier (for a minimum of 30 seconds).
At the end of this period, the creature is Suffocating.


When Suffocating, the creature can survive for a number of turns equal to its Constitution modifier (minimum of 1 round). Once this limit is passed, at the start of its next turn, it drops to 0 hit points.
It cannot regain hit points or be stabilized until it can breathe again.


The condition ends once the creature is allowed to breathe again.
