You summon a massive lightning bolt to annihilate a creature within range. Make a ranged spell attack against the target. If the attack hits, the creature takes 6d10 lightning damage and must make a Constitution saving throw. On a failed save, the creature is paralyzed until the end of it's next turn. Any creature with resistance to lightning damage has advantage on the saving throw.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 1st.
