Accelio

You fire 3 glowing red darts that continuously accelerate the farther they fly. Make an attack roll for each dart on a creature of your choice that you can see within range. A dart deals 2d8 force damage to its target if the creature is within 60ft. if the target creature is farther than 60ft the dart deals 4d8 instead, as the magical darts continue to accelerate.  you can direct the darts to hit one creature or several.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the spell creates one more dart for each slot level above 3rd.
