I'll turn that into a weapon strike, Mors- as Gift of the Emperor, like all Emperor powers, can only be used on a sword strike!
First of all, the first barricade has been cleared. So, to attack the next mundane, you first have to clear the second barricade! So, that is your first action, as you advance and clear that.
Next, you stab at the closest mundane there. You roll evens- that VERY nearly kills the Mundane as the Sword is a nasty weapon, but not quite. But then you activate Gift of the Emperor, and run him through instead! Your sword pierces straight through him, severing his spine, and killing him stone dead.
That is both your banked actions used. And then your action for this round will be, presumably, retrieving your sword!
Which means you are all caught up, Mors! Now I just need some defences from you.
