I came back to the game after a long time and when I was checking the characters I accidentally clicked on character edit in the wardrobe and there you have three options for what armor the character will be wearing (dots/circles) I noticed that epic armor was added as a third option (I think) and then I checked it on other characters and I found out that each class has different armor and so I would like to ask where can I get that armor?, I am mainly talking about old classes
