You call upon the power of the gale to transform you with their surging power. Until the spell ends, stormy winds swirl around you, your gestures crackle with lightning and thunder crashes at your feet with each step. You gain the following benefits:

• Attack rolls against you have disadvantage.
• You make Strength and Dexterity saving throws with advantage.
• Moving through nonmagical difficult terrain doesn’t cost you extra movement.

When you hit a creature with a melee attack, you can choose to channel a final surge of tempestuous might to deal an extra 2d8 lightning or thunder damage (your choice). The spell then ends.
