Aquatic Battle Tactics

The life you live in the oceans has taught you how to use water to your advantage, and you have learned how to abuse this training on land
You gain the following benefits:

• Increase your Strength, Constitution, or Charisma score by 1, to a maximum of 20.
• You gain proficiency in Spears, Tridents, Pikes, and Nets.
• When you make an attack roll against a target that is underwater with a weapon that does piercing damage, you have advantage on that attack roll.
• You can cast the Watery Sphere spell, once per long rest. Charisma is your spellcasting ability for this spell.
