Eis' Storm Install

With a booming yell from the top of your lungs, your heart of the elemental Air beats like thunder as the storming energy residing within you lets loose for the duration of the spell. During this transformation, you gain the following benefits:

• Upon activation, you force any creature of your choice within 30 ft of you to make a Charisma saving throw. If they fail the saving throw, they will be vulnerable to lightning and thunder damage. If they succeed the saving throw, then they will lose any resistances to lightning and thunder damage.
• Your flight speed is doubled.
• The amount of feet you move with the Tempestuous Magic feature is doubled.
• All spell attack rolls that deal lightning or thunder damage are made at advantage, and those with saving throws made to avoid damage against lightning and thunder damage are made at disadvantage.
• Add your spellcasting ability modifier to the damage of any spell that deals lightning or thunder damage.
• A swirling whirlwind surrounds you, making the area 30 ft around you difficult terrain for everyone else.
• All weapon attack rolls, be they melee or ranged, that target you are made at disadvantage.
• Any spell that uses wind deals 3d12 plus your spellcasting ability modifier in bludgeoning damage to any chosen target within the whirlwind upon the spell’s activation.

After this transformation, your current Sorcery Points and Hit Dice drop to zero, and you gain one level of exhaustion, which can be cured with a long rest.
