Avatar of the Storm

You endow yourself with speed and martial prowess fueled by the storm. Until the spell ends, you can’t cast spells, and you gain the following benefits:

• Your movement speed increases by 15 feet.
• You have advantage on attack rolls that you make with simple and martial weapons.
• When you hit a target with a weapon attack, that target takes an extra 2d12 lightning damage. You may force the target to make a Constitution saving throw, or be knocked back 5 feet.
• Upon ending your turn, all enemies within 5 feet of you take 1d4 lightning damage.
• You have proficiency with all simple weapons, and martial weapons.
• You have proficiency in Strength and Dexterity saving throws.
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that gives you extra attacks.
• You gain resistance to lightning damage.

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
