The teamcoco stream just showed Horror's upgrade - Despair. I didn't manage to get a screenshot of it, though.

The stream's over now. People asked them to show Tempest, but they didn't have Sera with them.
Holy flippin' balls. That horror is a sweet skill.
I'm going to be abusing the shizzle out of it 
Thanks dude!
edit: i've seen people talking about the devour skill. Do we have screenshots of it or it's upgrade? Same goes for dragon-rage?
EDIT 2: btw, I've been building a reaver today, and sice passives go cross-weapons (meaning s&b passives work for 2handers too and vica versa), here's a little tip, if you're building a 2Hander reaver, get warrior's resolve. If you can abuse dragon rage, you should basically continuously regain stamina, which can sustain your ring of pain. Which in turn lets you keep devour, which in turn, you hear it, lets you use dragon rage
