A Counterweight is an accessory sold by the Traveling Merchant and the Skeleton Merchant. It fires a second yoyo-type projectile after hitting an enemy with a Yoyo, dealing the same damage of the Yoyo and traveling towards it, then arcing over the player.
There are 6 variants, all functioning identically.
- Multiple equipped Counterweights do not stack. Only one will function at a time.
- The particular color equipped will display on a character, unlike the Yoyo Bag, which shows a random color.
- A Counterweight does not stack with the Yoyo Bag.
- Counterweights are real-world yo-yo accessories used to aid in tricks where the yo-yo is swung from the middle of the string rather than its end. Real-world counterweights are often patterned after (or made out of) polyhedral dice, and Terraria's follow suit: the Blue and Red Counterweights are four-sided (tetrahedral) dice, the Purple and Green Counterweights are six-sided (cubic/hexahedral) dice, and the Black and Yellow Counterweights are twelve-sided (dodecahedral) dice.
