You hurl a glowing green orb of energy shaped like a grenade towards a creature. Make a ranged spell attack against the target. On a hit, the target takes 4d6 force damage to the target creature. Every creature within a 30-ft radius of the creature must then make a constitution saving throw or take 1d8 force damage.

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