Warden's Bolt

You shoot a beam of pure radiant energy towards a target within range. Make a spell attack roll, on hit causing 2d6 radiant damage. In addition, the target must make a Wisdom saving throw. On a failed save, it has disadvantage on the next Wisdom save or check it makes until the end of your next turn.

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