So, the achievement This Side Up requires you to solve 8 of the new Legion archaeology rares, which is going to take 16+ weeks. And everyone has a color tint for their artifact appearance that is unlocked via the achievement. But do we have any kind of proof/confirmation whether or not you need to do this achievement on EVERY character you want that color tint on? Or do you only need to complete the achievement on one character to unlock the tint across all your characters?
The other tint requirements on that appearance tier sound like they could all be character-specific - complete your class hall campaign, unlock every artifact trait, and research your full artifact history. However, some of the other achievement-based tints on the next tier sound like they should be account-wide, such as Glory of the Legion Hero. Do we have any actual information on if any of the tints are unlocked account-wide?
