Water and Swimming

Bodies of water such as lakes, rivers, oceans, and swamps are pretty common in most locations, and sometimes characters need to cross them. Luckily, most individuals can swim, although some may be a lot better at it than others! Unless otherwise noted, characters treat any body of water as difficult terrain. The GM may also decide that some bodies of water, such as a river with a swift current or an ocean in a storm, are so difficult to move through that they require a successful Athletics check to swim in. In this case, it requires at least one action as well as any number of maneuvers to swim through the water from one location to another.

  If completely submerged in water, a character can hold their breath for a number of rounds equal to their Brawn characteristic. Once this number is reached, the character starts to drown and is treated as suffocating (see Suffocation, page 112) on each successive round until they surface or find some other source of air.
