Touch of Dawn

Your hand begins glowing with radiant light as you reach out and touch a creature within range. Make a melee spell attack against the target. On a successful hit, the target takes 3d8 radiant damage and has disadvantage on the next attack roll it makes before the end of its next turn.

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