Thunder Crash

When you cast this spell cause a massive blast of jolting energy to explode from you, right as you cast this spell you can choose to fly up to 50 ft to a desired unoccupied space before the explosion occurs. When exploding all creatures of your choice within a 30ft radius of you are forced to make a DEX saving throw or take 8d8 lightning damage and half as much on a success, they are also forced to make a CON saving throw or be stunned until they take damage or at the beginning of their next turn. After the explosion the area affected continues to surge with lightning until the end of your next turn causing all creatures who start their turn within the radius or if they enter the affected area for the first time on their turn to take 3d6 lightning damage if they fail a DEX saving throw.

When cast with a Lvl 8 spell slot or higher the explosion does an extra 2d8 lightning damage per Lvl of spell slot and the lingering electricity damage also increases in damage to 1d6 extra lightning damage per Lvl of spell slot.
