Eldritch Blast (Fiend, Efreeti)

A bolt of burning fire streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 2d4 fire damage and will take an extra 2 points of fire damage on their next turn.

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