Well, who wants to live forever anyway?
[4* vs 4*][5* vs 2] As the dragon flies forward and starts gobbling up your men with abandon, you let off the most powerful lightning bolt you have... to very little effect. The dragon notices the slight pain in its side and turns back to regard you.
[6* vs 5] You do your best to hide, but it turns out dragonfire goes around corners. Who knew? You are horribly burned. [6* vs 6*] You try a barrage of ice daggers instead, but they splinter against the dragon's impenetrable hide. [5* vs 2] The dragon moves around and snatches you up in its jaws. Your last experience is one of terrible, terrible pain.
You are dead.
I mean, seriously, what were you expecting?
It's a god damned dragon.
