Zurich's Chromatic Bomb

You lob a vial of chemicals at a target location that you can see within range. The vial explodes upon reaching the location, threatening all targets within a 5 foot radius sphere of that point. You choose acid, cold, fire, lightning, poison, or thunder for the type of vial you create, and then make a ranged spell attack against each target within the radius of the burst. After making an attack roll against each creature within the radius, each successful attack roll deals 3d8 damage of the type you chose.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st. Additionally, the area of effect increases by 5 feet for each slot level above 1st.
