Coordinated Assault

With a single word, you align your thoughts with an allied creature that you can see within range, allowing you to attack your target in a single strategic strike. The next time before the start of your next turn that you make a melee weapon attack against a creature that is within reach of both you and the target of the spell, the target can use its reaction to make a single melee weapon attack at the same time. If they do, both attacks are made with advantage, and both deal an additional 2d4 force damage.
