Fighting with Style: Upgraded

Just received this achievement today. I'm guessing it's because I had already completed the other 3 achievements required back in 2016/ 2017. I was doing the archaeology quests from Dalaran and completed This Side Up after turning in the quest.

As stated in the guide for unlocking artifact appearances (https://www.wowhead.com/unlocking-artifact-appearances-guide) you can still obtain this as the associated achievements have special properties to allow new players to earn this achievement. Seems all you have to get now is Forged in Battle and This Side Up

Information can be a bit confusing on the matter, atleast I know I was confused with the small amount of information out there and most importantly how contradictory everything is.

This achievement IS unobtainable (unless you have completed Power Realized & Part of History during Legion. However, the appearances that used to be linked to it are not anymore and are very much available in game today.

Completing the Class hall campaign will unlock the first 3 tints and completing This Side Up will earn you the 4th tint. You might need to relog for the appearance to show in your transmog collection.
