Hey Everyone,
I was hoping to get a hint on what I am doing wrong. I started to do all the bonfires yesterday and managed to do a few “steal the fire” horde city ones as well (I am a human alliance mage) Now the last one for the king of the fire festival quest I have to do is the fire in undercity. I found it in the courtyard of the ruins but as soon as I click it, I see the progress bar run to completion and then I die. When I check the combat log it says:
Flame of the Undercity Cleansing Flames hit You 4,546 Physical. (1.908 Overkill).
I am level 70 at the moment.
The other flame steal quests went ok, I got the quest and handed it in at exodar/ironforge.
Many thanks for your assistance,
Regards,
Mystic Wizard
Edit:
Allright, closing the game and battle.net client then starting it, using prismatic barier and greater invisibility then clicking the fire worked 
No clue which one of those caused it to work but I guess this might help other people out.
Good luck everyone I am off to ironforge to get my crown
