Blood Bolt

You create one dart of magical blood. The dart hits a creature of your choice that you can see within range. A dart deals 1d4 + your spellcasting ability modifier necrotic damage to its target. You heal yourself for half the damage dealt

The spell creates more than one dart when you reach higher levels: two darts at 5th level, three darts at 11th level, and four darts at 17th level. You can direct the darts at the same target or at different ones.
