Swim

Move through water in any direction. Halting movement keeps you where you are in the water unless there is a current, then you will drift at the speed of the current.

If your movement is reduced to 0 due to a Status Condition or a harmful effect, you will begin to float upward at a rate of 2u per Turn. If you are burdened with more than half of your Good spots filled in any one category or are carrying an item that is as heavy or heavier than you are and that wouldn't float, you will instead begin to sink at the same rate.
