Guild Wars 2

I think i did all of the “current achievements” but cant check cuz that section was descontinued. Is there something I need to do to “unlock” this section?

I believe knight of the thorn is on the side stories tab on restoring caladbolg story.

Have you try talking to Ridhais near the entrance of the groove? He should be standing near the Trahearne statue

Oh, and to unlock it you should finish the Heart of Thorn story and receiving the broken caladbolg first

If you already did and still can’t find it, either try to trigger it by talking to Ridhais on the groove, or use the search function on achievement
Hope this helps

It turns out it was just hidden. I had to talk to Ridhais to unlock it ;P

Ty for the info!
