SWIM

--- SWIM (SKILL) ---

This skill is very valuable to any character who plans on swimming across a
lake or beneath the ocean waves at some point in their life. Without it,
characters tend to just splash around a lot, slowly wearing themselves out
until they die from exhaustion. A character's rating in this skill is
automatically factored into their movement by the game code, so there are no
special commands or instructions to "use" it. You do not need to specifically
command your character to swim, simply continue to enter the direction you
want to move. This skill is aided by the Constitution attribute.
