Bleak Flame

You conjure a crackling flame of necrotic energy and hurl it at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes necrotic damage equal to 2d8 + your spellcasting ability modifier. If the target is a willing Undead creature, the attack automatically hits, but it instead regains a number of hit points equal to 1d8 + your spellcasting ability modifier. Constructs are immune to this spell. At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage or healing increases by 1d8 for each slot level above 1st.
