Death Mark

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 is marked by dark energy until the spell ends. You gain advantage on melee attack rolls made against a marked target. On your turn, you may use a bonus action to teleport to an  empty space within 5 feet of the marked target

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher attacks made against the marked target deal 2 bonus psychic or necrotic damage (your choice) for each slot level above 4th. Additionally, when you cast this spell at 7th level or higher, up to 5 allies of your choice also gain advantage on melee attack rolls made against the marked target.
