Yesterday I completed the new dungeon warlords ruin on master difficulty and once you beat it you can claim a triumph that gives you a ghost. However the triumph doesn't contain a ghost but instead the exotic sparrow of ghost of the deep as shown in my link. So I advice you to not complete this dungeon on master until it is fixed because the ghost is necessary for the title. Edit : it seems every triumphs rewards are bugged in this dungeon and are giving ghost of the deep stuffs, I just did solo flawless and I got the basic ghost of the deep emblem instead of the solo flawless emblem Have a nice day
