In Apex Legends, there are plenty of different cosmetics you can collect: Weapon skins, Legend skins, emotes, trackers, but none are as sought after as the Heirlooms. Heirlooms, or Heirloom melee weapon skins, are a special cosmetic that gives a character a special weapon to use for their melee attack. The Heirloom comes with unique actions both for the melee, and for idle and running animations.
In total, there are currently 13 Heirlooms in the game. Every Legend in the original lineup has an Heirloom, as well as a few of the Legends added to the game later. The earliest released Legend to not currently have an Heirloom is Loba, released in Season 5. The most recent Legend to have an Heirloom is Rampart, from Season 6.
