Arbogast gives ground and takes blow after blow on his shield, but the orc's onslaught is relentless. Even the strength lent to his limbs by the weeds he chews has fled, slowing his arm and robbing his body of breath. So it is that, when the orc's bent sword bites deep into his right arm, sending blood spurting from the wound and the Warden's Axe tumbling to the earth, he regards his plight with horror but without surprise.
Sore wounded and unarmed, there is no possibility of fighting back. He concentrates purely on surviving for as long as he may.
Arbogast is shifting into defensive stance and fighting defensively (using Brawl, since I've narrated that he's lost his axe). I'll sacrifice all three attack dice for +6 to his Parry.
On the other hand, I've learned that it's unwise to entirely dismiss one's chances in this sort of situation, so I'll roll the Feat die in case there's a lucky shield-bash in him...
Grimbeorn splits the smaller orc in twain, a searing blade through butter. Barely able to enjoy the small triumph, he is hit by the orc leader. He reels from the attack, getting himself set. He attacks back from a defensive position to protect his comrades.
