Swim Bladder and Propeller (Embedded Component)Edit
This warforged component takes the form of an air-filled sac which can be expanded or contracted at will and a propeller or set of propellers which allow you to move underwater as if you were naturally aquatic.
This component grants you a swim speed equal to your land speed. Because of this, you gain +8 to Swim checks to perform some special action or avoid a hazard. You can always choose to take 10 on a Swim check, even if distracted or endangered. And you can use the run action while swimming, provided you swim in a straight line. You still do not need to breathe.

Rustproof Coating (Attached Component)Edit

You gain +4 to saving throws vs all spells with the water descriptor and all spells or effects which rust metal, such as rusting grasp or the touch of a rust monster.
Moreover, you suffer no rust-related ill effects from prolonged exposure to water or moisture.
