WW: Bombarda Maxima

A bright streak flashes from your wand or fingers towards a point in range that you can see, it then explodes in a 20ft Radius on that point.
Any creature inside this radius must make a DEX saving throw. On a failure they take 6d10/Force damage or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
