Arcane Chain

You pull the weight of two creatures towards each other. Make a ranged spell attack against a creature within range. On a hit pick one creature within sight and within 30 ft of the target, both creatures must make a Strength saving throw. If both creatures fail they are pulled towards each other crashing at the mid point between them and each take 6d6 force damage. If only one creature fails it is sent crashing into the other dealing 4d6 force damage to each creatures. If both creatures succeed the spell fails. Both creatures must be of size medium or smaller.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damages increases by 1d6 for each slot level above 3rd.
