As part of your movement and reaction action you are briefly engulfed by a flash of turquoise and take on the form of lightning.
While in this lightning form you gain resistance to bludgeoning, piecing, and slashing damage from nonmagical sources and can move up up to your speed to an unoccupied space you can see within range. If you end your turn in an occupied space, you are shunted to the nearest unoccupied space and take Force damage equal to twice the number of feet you have moved. You can NOT make weapon, ranged, or ranged spell attacks, but can otherwise cast and concentrate on spells.
Any successful attacks of opportunity made against you with a conductive melee weapon (iron, steel, etc.) while in this form, will force the attacker to make a Constitution saving throw. On a failed save, the attacker take 2d4 lightning damage.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d4 for each slot level above 1st.
Crestfallen: While in this form, if lightning or thunder damage would down or kill an enemy you may immediately expend a spell slot of equal or lesser value to the one used to cast Tempest Step. You may cast this spell as a free action.
Unique Ritual: Casting this spell as a ritual does not consume any spell slots and may only be done so outside of combat for cool movement effects.
