race features:
Amphibious: You can breathe both air and water. Additionally, you have a swimming speed of 30 feet.
Shifting Feature: While shifted, you can use your rows of razor teeth to make an unarmed strike as a bonus action. If you hit with your bite, you can deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
