Eldritch Blast (Undead/Undying)

A ray of necrotic energy springs toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 necrotic damage and can't regain hit points until the start of your next turn.

The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.
