Counterweights

A Counterweight is an accessory sold by the Traveling Merchant and the Skeleton Merchant. They fire a second yoyo-type projectile after hitting an enemy with a Yoyo that travels towards the Yoyo, then arcs over the player. They can also be used to craft a Yoyo Bag.

Counterweights all appear to be dice. The blue and red varieties appear to be tetrahedral dice, the purple and green ones cubic dice, and the black and yellow ones dodecahedral dice.



Trivia
These could be a reference to "side effects", yo yo accessories made by One Drop that are weights on either side of the yo yo.
