So, Sigun Tickplanks, Militia Commander of Swordworld and total badass finds himself at the front when a vile force of goblin lashers arrive. Being lashers, and there being like eight of them, one of them gets through, tearing up his shoulder and taking off his shield hand. What he does afterward is the stuff of legends.
He sprints through the 1-square tunnel entrance, through the group of lashers. I assume he's doing what any injured dwarf trying to retreat would do: run blindly into danger. I guess that might actually have been what he was doing.
Apparently, about five seconds later, he turns back, I check his status, his shoulder has gone from cut open to dented("I ain't got time to bleed!") and he's hunting down the guy that was chasing him away from the entrance. He cuts him apart and heads back into the fray, and goes to town on the goblins still trying to fight through the entrance. At some point, the goblins decide it isn't worth it, and go to retreat. He can't catch them all, but few of them live.
Fortress life comes out of alert mode, and only now does he head down to the hospital for treatment.
A few ingame days later, a lazyass diagnostician decides to go check him out. As it so happens, he has wolverine'd all of his injuries away except for his hand. But whatever, he's a dwarf. Last I checked, he was carrying around his new shield in the same hand as his axe.
He is incredibly quick to heal.
