Mariner

Your training in and around water has given you the ability to best others when you're in your enviourment. 

You gain the following benefits:

• Increase your Strength or Dexterity score by 1, to a maximum of 20.
• You gain a swimming speed equal to your walking speed
• When you are in contact with a body of water you gain a +1 AC bonus and difficult terrain doesn't slow you down if it is caused by water (this effect applies too when you are on a ship, boat or beach. Thus a ship that is being tipped over does not slow your movement down.)
