The Bleak Reach
Fighting a 'small mob', your successes decrease their 'mob size/HD' accordingly. As I am imagining these things as simply, thuggish brutes of 1 HD each ...
As Xin swung his fist, it was as though the earth and heaven itself channelled power though our young hero's body, for the mere force of the blow ... the power generated by his fist travelling though the space between he and his enemy ... arced out like a wave of destruction, shattering bones and stones that Xin's fist never even reached.
As the lead monster-thing's head was ripped to the side in a sickening crack, several of his cohorts were knocked off their feet.
Xin's force of will that powered the blow ruptured and shattering a nearby rock, exploding it from within sending shards and fist-sized chunks brutally into the head of a nearby mongrel man.
In screams of pain and agony, surprise and fear, four of the brutish creatures fell with this one blow.
"When the foes are given some reason to flee, they roll 2d6; on a roll higher than their Morale, they retreat, surrender, or otherwise stop fighting".
- rolled 9 using 2d6. Moral 9.
Xin could see the remaining mongrel men stand, their eyes widened by fear and sudden uncertainty.
They had just witnessed something truly fearful, and their spirits were rattled.
But not quite enough for them to retreat, surrender, or otherwise stop fighting ... but the proverbial fear of God was within them now, and they were now advancing much slower and cautiously than they had before.
I am going to give them a -1 penalty to their attack rolls, to represent this
But advance they did, weapons out before them; and suddenly, as one group, they screamed and raged, and charged Xin as a mob ...
- rolled 9 using 1d20+3 (6). Attack against Xin.
... but their fear, and their lack of cohesion was, well, ridiculous. Only a few even got close enough to make a viable strike; most of them instead to scared to get close enough to the strange young man before them. And the few that actually got into weapon strike range were swinging wildly and fearfully; one even had its eyes closed in fear of seeing his spear strike and draw the wrath of the godling human.
Mongrel Men mob now down to 8HD.
No damage to Xin.
Xin's turn to act again
