Discus of Light

You hurl a glowing disc of holy light at a target of your choosing within 60ft. The target must make a Dexterity saving throw, taking 3d6 radiant damage on a failed save, or half as much on a successful one.

At the start of your next turn, all creatures in a straight line between you and the ring must succeed on a Dexterity saving throw or take 1d6 radiant damage as the ring flies back to your grasp.

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