(Well, maybe you will get stoved rather than skewered...)
The Chiorc flings his ball and chain upwards and your sword is flung away behind it (where wr can say it lands on an orc, for comic effect). Your axe meets the approaching sword of the orc, but both your weapon and your strength are the stronger and with a mighty clang the orc is thrown back, his weapon sliced off at the top.
Then the ball swings into your side. It feels as if a troll just scooped you up and threw you away. Your mail is dented to the point where it tears and you think a rib breaks, but it is hard to concentrate as you fly a short distance through the air and land heavily nearby.
The Chiorc laughs, nastily...
He is 'only' a big orc. He doesn't like the sun (and if it were not for that sudden burst of low cloud he'd be at a disadvantage for this fight, as would all the Orcs) and he fears a superior enemy. Other than that, you may as well ask the weak point of Aragorn; shove a sword through him and he is as dead as anyone else but doing it is the trick.
With the front lines mostly shattered, orcs are starting to stream towards the middle from there also, ignoring the fight of their leader. But one man, maybe with more bravery than sense, has stayed with you to fight him, Talin.
Oooh, so you did.
Well, with Farael and Aranui doing their Dunadain double (de doo dah dah) they are slowing the break in the right half of the line, and you are there stopping anyone coming through at all.
If you went to the other side some will start to go through that first hole, but not many. You might seal the other gap also.
Meanwhile, some 12 orcs are preparing to give battle in the middle and another ten are dashing in from the front lines where most have fled.
William, yes, you may climb up if you wish... Vardalain, you are climbing up the damn thing again... you are getting pretty tired of this!
"I don't have a clue how to use a spear!" yells your comrade, Talin. The Chiorc flips up its ball and cahin and wraps a length around its arm in preperation for a short blow, although you are still at range.
