As you hold your hands together, energy gathers in your palms and releases in a line when pushed outwards. Each creature in a 30-foot line must make a Dexterity saving throw. A creature takes 3d6 radiant damage on a failed save, or half as much damage on a successful one.
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.
