Deathblow + 2 Weapons

[ChasmGasm]

Just curious if anybody know whether or not Deathblow(Technique/Two-Handed) hits with both weapons or not? And is the increase in damage going to be physical? Would the bonus damage apply to both weapons? I'll try to level this guy up and see the old fashioned way, but I just wanted to see if anybody could give a definitive answer one way or the other.


Edit:
I found out all by myself! "You can't use this talent without a two handed weapon..."
