Underwater Combatant

The adventuring life often leads to discoveries far below the waters surface. Your time spent in such locations have granted you the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You gain a swimming speed equal to your walking speed.
• You have advantage on Strength (Athletes) checks made to tread through rough water.
• You have advantage on Constitution saving throws made to hold your breath or keep from drowning.
• Melee weapon attacks made while underwater no longer impose disadvantage.
