Hit or miss, the orb then explodes. The target and each creature within 10 feet of it must succeed on a Dexterity saving throw or take 4d4 radiant damage. this spell does double damage to the environment and objects but does half damage to constructs.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the radiant damage increases by 2d4 for each slot level above 1st.
