Blackened Smite

The first time you hit with a melee weapon attack during this spell’s duration, your weapon gathers pulsing shadows or vibrant fire (player's choice), and the attack deals an extra 2d6 slashing damage to the target. Upon using this smite, the player specifies if shadow or flame has surrounded the weapon used, and an additional 1d4 of damage is dealt as either necrotic or fire depending on this choice.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 1d6 (slashing) and 1d4 (necrotic or fire) for each slot level above 1st.
