How is Lorric coping with the loss of his foot?
As well as any dwarf could be expected to: as in, if they don't die or snap, they just shrug it off. You'll be on a crutch for the rest of your life (Toady, why haven't you implemented prosthetics yet?), but you can continue to work and live as normal. You will be a bit slower than usual, and have less-than-stable footing in a scuffle, but are otherwise unchanged.
Coffin for me, yo!
Also, if Hobbie has a child, redorf me into him/her as Hobbieson. Or another dorf. Whatever's free.
Yup. Already have you interred in the Hall of History, and I think you have children, so the line will continue.
So apparently I'm a real boss. That makes me a Legendary what else in addition to mining?
I believe that a moody dwarf's highest skill is counted when making an artifact, and your highest skill was Mining. Which means that, unfortunately, you gained no new skills from your artifact.
More beatings. You could imagine this being a vicious cycle.
The Dwarven Justice demands it!
Gets it out of his system by killing someone - takes a beating - angry again, gets it out of his system by killing someone - takes a beating - angry again, gets it out of his system by killing someone...
This is actually how a lot of tantrum spirals start. Which is why Stoker McAngry had to be melted down. He wasn't able to pour some cheerup on his paincakes, and his apparently hulk-like strength would invariably kill somebody important/popular and piss off the rest of the fort. I don't enjoy deliberately killing or dooming my own dwarves (unless they're an unrepentant cocksucker noble), but this was the most expedient way to handle the problem. Hm... maybe some "isolation time-out" cells are in order....
