Veles's Piercing Flourish

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails.
On a hit, the target suffers the attack's normal effects, and the attack deals an extra 3d6 piercing damage to the target. Until the end of this turn, your movement does not provoke opportunity attacks from the target.

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