Burnishing Not working

eric ehresman

        Burnishing says to burnish to upgrade Aura, but it is now telling me that all sockets must be of the same aura level in order to burnish, this does not make any sense to me, please help.Thank you

        each must have the same level , if you have 2 of level 1 and the third is level 0 then you need to click the third and get it to level 1 then all 3 can reach next level 2

        Hello there!
        like the above player mentioned, for you to advance into the next burnish aura level, you have to make sure all the sockets in that artifacts are same level each step. (all +1, all +2 ....etc)
        good luck.
