Hunter Rumours in OSRS came out with the Varlamore Part One update on March 20, 2024. The Hunter Guild content page also describes Hunter’s Rumours as part of that update.

What it was

  • It was introduced as a Hunter Guild task system, similar in spirit to Slayer tasks or Farming Contracts.
  • Players access it through Verity in The Burrow at the Hunter Guild.

Extra context

  • The broader Varlamore Part One expansion launched on the same day, which is why Hunter Rumours are tied to that release date.
  • Some later guides and videos discuss it as a newer training method, but they are referring back to that March 2024 release.

Bottom line

So the quick answer is: March 20, 2024.
