Black Arrow (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
For the duration, any time you hit with a ranged weapon attack, you deal an extra 1d6 necrotic damage. If this attack reduces a Medium or Small humanoid to 0 hit points, the humanoid must succeed on a Constitution saving throw or immediately be raised as skeleton, as if you had cast animate dead.
