Emerald splash

You create 3 emeralds that fire in a straight line. All the emeralds hits a creature of your choice that you can see within range. An emerald deals 1d4 + 1 force damage to its target. The emeralds strike one after another extremely fast.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more emerald for every level you go up.
