A heartbreak pottery sherd is a pottery sherd that depicts a broken heart. It can be found in trail ruins.
Obtaining
Breaking
Breaking a decorated pot causes it to drop all of the bricks and pottery sherds used to craft it, meaning it drops each of the heartbreak pottery sherds that were used to craft it.
The probability of the heartbreak pottery sherds generating in trail ruins has been changed from 1/11 to 1/12.
The player now gets the advancement "Respecting the remnants" when they brush a suspicious sand or a suspicious gravel to obtain a pottery sherd, and "Careful restoration" when they craft a decorated pot using 4 pottery sherds.
