Ocean Diver Barathu

SFS Note Change the second sentence to read “When you do this, your body increases its size to Huge, and you can only use your swim Speed to move.”
Your thirst for knowledge saw your gaze turn toward terrestrial exploration. Rather than the vastness of space or the surfaces of other planets, you've chosen instead to explore oceanic depths. Here you've found creatures and biomes as wondrous as those found in the far reaches of the galaxy. Such incredible findings must be shared, and you've adapted yourself to that task. You gain the ability to breathe underwater, and you gain a swim Speed equal to your fly Speed. Additionally, you gain the Living Submersible action.
