Sorcerer
Base Class: Sorcerer

Your 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 perhaps you were born during a howling gale so powerful that folk still tell stories of it, or your lineage might include the influence of potent air creatures such as djinn. Whatever the case, the magic of the storm permeates your 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. It is said that they are as fast as the lightning strike upon the land.

Level 3: Wind Speaker

The arcane magic has been awakened. Your 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. Additionally, you gain advantage on Charisma (Persuasion, Intimidation) check against Primordial.

Level 3: Tempestuous Magic

Your magic causes whirling gusts of elemental air to briefly surround you.

Immediately before or after you cast a spell of 1st level or higher, you can spend bonus action to fly up to 10 feet without provoking opportunity attacks.

Additionally, when you reach a Sorcerer level specified in the Storm Spells table, you thereafter always have the listed spells prepared.

Storm Spells
Sorcerer Level Spells
3 Shatter, Gust of Wind
5 Call Lightning, Lightning Bolt
7 Storm Sphere, Watery Sphere
9 Maelstrom, Control Wind

Level 6: Heart of the Storm

Your heart is filled with thunderous surge of lightning magic blessed by the Primordial.

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 up to your Charisma modifier of your choice that you can see to take lightning, or thunder damage depends on the spell damage type (choose each time this ability activates.) The damage equal to half your sorcerer level (round down) plus level of the spell slot used.

For example; a level 7 sorcerer casts Lightning Bolt the 3rd-level spell on enemies, causing them to take 6 extra lightning damage from this feature. (3 damage from Level 7 rounded down, 3 damage from casting 3rd-level spell)

Level 6: Storm Guide

You gain the ability to subtly control the weather around to your will.

You can use an action to cause the rain to stop falling in a 30-foot-radius sphere centered on you. You can end this effect as a bonus action.

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.

Level 14: Storm's Fury

When you are hit by a melee attack, you can use your reaction to deal lightning or thunder damage to the attacker. The damage equals to 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.

Alternatively, you can push yourself away in a straight line for 10 feet from the attacker, without provoking opportunity attack. Using the feature this way doesn't either deal any damage or push the attacker away.

Level 18: Wind Soul

For a moment, our nimble feet may leave the blessing of land.

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.
