The restless spirits of pandaren and Allied Races can return to the mortal plane as Death Knights in the upcoming Visions of N’Zoth content update.
Read the complete preview here.
Just as an fyi, we made a correction. We deleted a typo that incorrectly stated that pandaren can receive Heritage Armor by leveling to 110.* Apologies for the confusion.
You’ll need to do it on an Alliance character to unlock them.
All Allied race Death Knights start at level 58.
There are a couple of bugs with Wraithchill that were present in 8.2.5, and are fixed in Visions of N’Zoth. Looking through them, they appear to be unintended conflicts with other things that made the illusion go away.
Again – fixed with the update coming in 4 days.
Yes. From the blog post linked in the OP:
Heritage Armor for Allied Races characters can be obtained by leveling to 110.
