Ok, so I was just looking at the "horns" on the Titan, which look so kick ass I might have to choose that as my class instead of a Warlock (but I doubt it). Anyways staring at the "horns" in high def, check out the link, it seems to me like the horns are possibly a backlit gas escaping from an Awoken's helmet. Each of the gas "horns" looks as though they are emanating from cracks in the Titan's helmet. This could be pretty dern cool and gets my mind pulsating. Was her helmet damaged on her way to the Hell Mouth? Or perhaps these are battle scars from a past engagement. I figure that the light could either be coming from an Awoken, similar to elves in Lord of the Rings. But it also could just be light from the hardware inside of the helmet, possibly the hud. Anyways, who knows right? But those holes on the top of her helmet totally look like cracks to me. I guess only time will tell what kind of badd assery this naughty Titan got into to acquire her booty.

I had the same question. I thought these "magic eyebrows" could be some type of positive buff. Also, they were stylized in a way that felt very "Awoken" race to me, so perhaps behind the mask it could be that race and this was some kind of simple cosmetic effect.

well the awoken concept art shows kinda glowy eyes, im guessing that's what it is.

But the horns could show up when it was activated. I really like the idea of that ability.

I like the ability ( call it Berserker mode ) I don't like having an ability tied in to a specific piece of armour. Some things should just be cosmetic.
