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.



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.

The Counterweight sprites seem to be based of Dice, the Blue and Red Counterweights are four sided dice, the Purple and Green Counterweights are 6 sided dice, and the Black and Yellow Countereights are 12 sided dice.
