Drowning

Help Drowning

 
Rooms that are flagged underwater require the ability to breathe underwater,
or they will cause suffocation damage each tick and will result in eventual
death by drowning if hit points drop to zero.

The ability to breathe underwater is available through a number of options.
The most common is the
underwater breathing spell; however, Tritons have
the racial ability to breathe underwater, the ability to breathe underwater
is granted on a few pieces of equipment, and the
gills wish ('help wish')
also adds the effect.

Flight and boats allow movement into and out of underwater rooms, but will
not prevent drowning damage from occurring.
