Volatile Brew

You create a roiling brew of volatile alchemical power and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 acid damage. Hit or miss, the vial then explodes. The target and each creature within a 10 foot sphere of it must succeed on a Dexterity saving throw or take 2d6 thunder damage. However, if you roll a 1 on the attack roll (cannot be altered or re-rolled), you must immediately make the Dexterity saving throw with the caster as the target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the thunder damage increases by 1d6 for each slot level above 1st.
