Eldritch Blast

0-level (Cantrip) Evocation

A beam of crackling energy streaks towards a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 force damage.
At higher levels: The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and our 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.
