5-level Evocation
You gesture to a point you can see within range, and an explosion of energy that erupts from that point. You choose acid, cold, fire, lightning, poison, or thunder for the type of explosion you create. Each creature in a 30 foot radius sphere centred on that point must make a Dexterity saving throw, taking 5d10 damage of the type you chose on a failed save, or half as much damage on a successful one.
When you cast this spell using a spell slot of 6th or higher, the damage increases by 1d10 for each slot level above 5th.
