So while the treasure hunter personality is disappointing compared to almalexia's lantern, after a while its convincing enough to suspend disbelief of having a lamp at night and in delves.
While mucking around the crown store recently, had a look at those weapon skins.. at first glance they're very average, but when previewed in game, they have a flame effect on all of them.. which did cast a glow on your character in the preview window. Since this is a problem with treasure hunter.. i took a gamble and yes it works!
For an extra 2.5k you can have the torch glow effect when your weapons are out too!
I was kinda hoping that because the bow at least is burning in 2 points, the glow might have a larger radius than the treasure hunter personality.. but it doesn't.. its still that teeny tiny circle under your feet. Better than nothing though.
ps. The designs were all lesser than what i have currently.. except the staff.. the staff is absolutely awesome.
So what's it going to take to change the lamp radius? Its barely bigger than circle shadows from early days in wow.
