Storm Sorcerer

Overview

These sorcerers' innate magic comes from the power of elemental air. Many with this power can trace their magic back to a near-death experience caused by the Great Rain, but some were born during howling galse so powerful that folk still tell stories of them, or a sorcerer's lineage might include the influence of potent air creatures such as djinn. Whatever the case, the magic of the storm permeates their being.
Storm sorcerers are invaluable members of a ship’s crew. Their magic allows them to exert control over wind and weather in their immediate area. Their abilities also prove useful in repelling attacks by sahuagin, pirates, and other waterborne threats.

Features

1st Level - Wild Speaker

The arcane magic you command is infused with elemental air. You can speak, read, and write Primordial. Knowing this language allows you to understand and be understood by those who speak its dialects: Aquan, Auran, Ignan, and Terran.

1st Level - Tempestuous Magic

You can use a bonus action on your turn to cause whirling gusts of elemental air to briefly surround you, immediately before or after you cast a spell of 1st level or higher. Doing so allows you to fly up to 10 feet without provoking opportunity attacks.

6th Level - Heart of the Storm

You gain resistance to lightning and thunder damage. In addition, whenever you start casting a spell of 1st level or higher that deals lightning or thunder damage, stormy magic erupts from you. This eruption causes creatures of your choice that you can see within 10 feet of you to take lightning or thunder damage (choose each time this ability activates) equal to half your sorcerer level.

6th Level - Storm Guide

You gain the ability to subtly control the weather around you.
If it is raining, you can use an action to cause the rain to stop falling in a 20-foot-radius sphere centered on you. You can end this effect as a bonus action.
If it is windy, you can use a bonus action each round to choose the direction that the wind blows in a 100-foot-radius sphere centered on you. The wind blows in that direction until the end of your next turn. This feature doesn’t alter the speed of the wind.

14th Level - Storm's Fury

When you are hit by a melee attack, you can use your reaction to deal lightning damage to the attacker. The damage equals your sorcerer level. The attacker must also make a Strength saving throw against your sorcerer spell save DC. On a failed save, the attacker is pushed in a straight line up to 20 feet away from you.

18th Level - Wind Soul

You gain immunity to lightning and thunder damage.
You also gain a magical flying speed of 60 feet. As an action, you can reduce your flying speed to 30 feet for 1 hour and choose a number of creatures within 30 feet of you equal to 3 + your Charisma modifier. The chosen creatures gain a magical flying speed of 30 feet for 1 hour. Once you reduce your flying speed in this way, you can’t do so again until you finish a short or long rest.
