Swimming This is a skill that every player has some skill in. Swimming drains stamina, so attempting to swim unaided across a vast stretch of water such as an ocean or lake or tidal river can sap all the stamina from a player, causing them to drown. A player may swim on the surface or can learn the skill of freediving. A freediver can swim down to a depth of around ten metres without the need for breathing aparatus, allowing them to gain access to underwater entrances or retreive goods from a the bottom of rivers, etc. Floatation devices can be used to assist swimmers across broad stretches of water. Players should be aware that carniverous creatures live in deep water.
