Deadly Flourish

The next time you hit a creature with a ranged weapon or spell attack before this spell ends, the target must succeed on a Strength saving throw or be restrained by a small magical field surrounding the target. A Large or larger creature has advantage on this saving throw. If the target succeeds on the save, the field dissipates.

While restrained by this spell, the target takes 1d6 force damage at the start of each of its turns. A creature restrained by the field or one that can touch the creature can use its action to make a Strength check against your spell save DC. On a success, the target is freed.

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