Revenant Mask and leveling
It’ll be just like all the other starter profession hats (glowy eyes, hoods, colored floating gems, etc). It’ll be a skin in the wardrobe and if you want it on higher statted gear you’ll have to transmute.
Though you could keep the early version and put it on for RP and screenshots.
Keep in mind that you can make and delete two other revenants and then you’ll have all three blindfolds as skins, and your guardians and warriors can wear them too.
edit: The above is my opinion, not something stated by devs. But I can’t see it working any other way, especially as they did a lore blog for RPing revs in which they said the blindfold was there to help focus, it didn’t mean the eyes underneath didn’t work, and not every rev would necessarily cover their eyes.
Levelling a character doesn’t take long. I’d just bare the lack of blindfold for the few days/weeks it takes to level a character to 80, then transmute it onto a permanent piece of Exotic/Ascended gear you want to use.
You didn’t find any info because there is no reason for 1 type of skin for 1 specific class have a different mechanic.
Revenant blindfolds will be a regular skin like any other.
(and the other 8 elite specs maxed too)
