Bleeding Smite

The next time you hit a creature with a melee weapon attack during the spell’s duration, your attack causes the target's injury to linger and hemorrhage, and the attack deals an extra 1d6 damage to the target. Additionally, if the target is a creature, it must make a Constitution saving throw or it's speed is halved and it cannot take reactions until the end of it's next turn. Also, the creature takes an additional 1d4 damage the next time it makes more than one attack or the next time it moves during the spell's duration.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the initial extra damage dealt by the attack increases by 1d6 for each slot, and the additional damage  dealt to the target if it makes more than one attack or moves increases by 1d4 for each slot.
