Stormcaller - Elemental Air (Revised)

Humanoids that find themselves with elemental abilities manifest powerful, sometimes uncontrollable, magical power. Sorcerers that draw their power from the Elemental Plane of Air focus on flying high and bombarding enemies far below with blasts of lightning and thunderous shockwaves. They hate confined spaces, and are content to wheel in the clouds high above. 

Living Storm

At 6th level, you learn the call lightning spell. When you cast it, you can center the cylinder on your space, and the cloud moves with you. In addition, you gain resistance to thunder and lightning damage. 

Elemental Wings

At 1st level, you gain a flying speed equal to your walking speed. When you fly, an elemental effect appears on you. This can appear however you want. For example, you could manifest avian wings made of thunderheads, or have wind swirl around you. When you fall, you descend 60 feet per round and take no damage from falling. At 14th level, your flying speed equals twice your walking speed. 

Elemental Spells

At 1st level, you learn the gust cantrip and the thunderwave spell. You also gain spells when you reach certain levels. At 3rd level, you learn the spell gust of wind. At 5th level, you learn the spell lightning bolt. At 7th level, you learn the spell storm sphere. At 9th level, you learn the spell control winds. These spells don't count against the amount of sorcerer spells known.

Elemental Conversion

At 14th level, when you cast a spell that deals acid, cold, fire or poison damage, you can expend an amount of sorcery points equal to 1 + the spell's level and change the damage type to lightning or thunder damage (your choice).

Aerial Bombardment

Starting at 18th level, you can deal extra damage if you target a creature at least 50 feet below you with a spell that deal lightning or thunder damage. The extra damage equals (1 + the spell's level) × your Charisma modifier.
