I'm sorry if this has been posted, but I couldn't find anything about it with search.
I just discovered this yesterday, I'm not entirely sure how it happened, but here it goes..
With the ability Mend Pet, I was about to heal my pet, and it died at the exact moment I clicked. After that my hands were glowing like when you cast hearthstone, or druids heal... I would get the sound, and the glow...
Then later on I was trying to heal my pet again, it was halfway down a stair, so I got the mssage "Target not in line of sight" and then my hands started glowing again.
To get the glow away you have to click Mend Pet again. Also it doesn't seem like other players can see it.
I hope someone can find out how it exactly works![]()
