There has been a lot of discussion on the forums on how to actually obtain the hidden artifact weapon skin for Havoc. Turns out there’s a simple solution and you don’t need to spend hour farming Candraels Charm.
The main reason why no one could figure this out is you need your Artifact Knowledge to be level 5. If you leveled a demon hunter at the start of the expansion you should have at least 4-5 Artifact Knowledge by now.
Follow the guide below.
Using the demon hunters wings you can descend into Felsoul and land on top on Downfall. I jumped from this location in Dalaran.
It’s a relatively easy fight, I chose to kill Downfall using the Vengeance spec to make my life easier. Just make sure to use your wings when Downfall knocks you in the air.
To confirm I did not have Candraels Charm, I killed Downfall and he dropped the Guise of the Deathwalker.
Good luck to all the demon hunters searching for the Guise of the Deathwalker! I will be releasing the Vengeance skin once it drops for me!
