Vampiric Missile

You create a glowing dart of magical force. The dart hits a creature of your choice that you can see within range. A dart deals 1d4 + 1 necrotic damage to its target. Once the damage has been dealt, the missile bursts forth from target at the point of entry and flies back to impact the caster who then receives a number of temporary hit points equal to the damage dealt.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each level above 1st.
