Every time I view my profile I see a box next to that neck that says, “You have unlocked a new power. Visit the Heart Forge to unlock it.” But when I get to the Heartforge, there is nothing to unlock! This message is driving me crazy. My powers are all level 1. Clicking on them, the heart forge, switching each power in and out of the Heart does nothing. The message reappears whenever I open profile outside of Heart Forge chamber. Help!
Might be due to a corrupt UI, because of the new patch. Have you tried a UI reset?
I’m having the same problem.
Did you also try the UI reset?
By chance an essences unlearned in your bags?
If not UI it is my next thought.
Could it be the Perseverance trait that unlocks at Azerite level 52?
Here is a screenshot of mine that shows how it looks when you are viewing the Heart Forge. I have marked the trait with an arrow to show its location.

UPDATE: I was wrong about the level needed to unlock the new trait. That unlocks at 52. Thanks @Lleztrah for helping me see the error.
I reset the UI and I’m at heart level 52.
Do you have an Essence in your bags like Mastadôn suggested?
Look at the picture Kyzera posted then go to the heart of azeroth and click on that little tiny diamond. At 52 you get a stam increase but you have to click on it to activate it.
Thank you for this post. I had mistakenly said that the heart needed to be 53, but you are correct in that the new trait unlocks at 52. I have corrected my post above.
That is exactly what it is. I didn’t even notice the little diamond there. It pretty much melds into the background.
Thank you <3 Kyzera
Thank you so much! I didn’t notice that little thing was highlighted!
You’re welcome.
You’re welcome.
THANK YOU JEEGUS. Blizz seriously please work on making these little “hidden” trait upgrades easier to find in the UI. It was driving me crazy until I found this thread.
you so rock… It was the perseverence trait… didn’t even notice that thing!
legend, that was the issue i had too
I couldn’t unlock this perseverance trait at 52 on my Warlock until I found I had an unlearned enchanting recipe in my bags. As soon as I learned the recipe I could unlock the trait.
Thanks so much Kyzera, the Perseverance was my issue.
You’re welcome.
