Drowning

An Acrocanthosaurus Being Drowned by a Mosasaurus

When any non aquatic creature goes underneath the water, they will begin to lose breath. Larger creatures have a longer amount of time before running out of breath than smaller ones. When the breath bar is exhausted, a player will lose 15% of their health every 1.5 seconds until dead. Returning to the surface of the water will refill the breath bar. Aquatic creatures have no breath bar, and instead must manage their air supply.

Certain cave systems are designed deliberately such that certain areas are accessible to land animals only at low tide. Air pockets, rising water levels, and breath timers are balanced around design of these areas such that it will kill players trying to pass at the wrong time in the tidal cycle.

There are currently no means by which a player can alter the time in which they can hold their breath.

Creatures possessing a grab can use it to their advantage to deliberately drown their opponents. Sometimes this is a safer way to kill one's prey than to attack them directly.

This mechanic should not be confused with air, which is a resource managed by aquatic creatures.

It has yet to be decided whether semiaquatic creatures will utilize the air resource, or will have a breath bar.
