Regina Maris, Anima Tempestas

The sea's call to you as if you are the embodiment of the tides itself. Almost as if your very soul has been intertwined with the oceans as your tears flow. The ocean waves grow violent, when you speak. The water calms. And when you are needed most. The ocean will never leave your side again.

Avatar of the seas
At the start of initiative, you gain the effects of the spell storm of vengeance as a storm appears above you, it becomes your lair and acts on initiative 20 (losing initiative ties) requiring no concentration.

If you take lightning or thunder damage, you may use a reaction  to take take an additional action as your body becomes energized. When you use this ability you must wait till you take a short rest before you can use this ability again.

Your powers of the storm are nearly unrivaled. Whenever you cast a spell that does lightning or thunder damage. You may do one of the following abilities as a free action per turn.

• You may double the damage dice on the spell and hostile creatures in the spells range auto fail the DC and cannot heal for one round.
• Creatures caught inside of your lightning or thunder spells heal rather than receiving damage from the spell.
• If a creature were to die from your spell. You may regain sorcery points equal to your charisma modifier.
