Thunderbolt

A deep blue streak of lightning lances out towards a target within range and causes a deafening explosion heard up to 1 mile away. Make a ranged spell attack against the target. On a hit, the target takes 10d10 lighting damage. Each creature in a 30-foot-radius sphere centered on the target must make a Constitution saving throw (the target of the spell automatically fails the saving throw). A creature takes 4d10 thunder damage and is deafened for 1 minute on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the lightning and thunder damage increases by 1d10 respectively for each slot level above 5th.
