Defiant Strike

You brandish the weapon used in the spell's casting and make a melee attack and damage roll with it. Each creature within 5 feet of you that has an AC equal to or lower than the melee attack roll's result takes radiant damage equal to the damage roll + your spellcasting modifier.

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