I just started playing this mod, after spending 3 hours reading the whole thread and learning about the hilarious diseases.
Anyway, I'm adventuring as a steel axedwarf, and I picked up a nord axeman and a nord hammerman and went around the place killing dragons and hydras and such for the dwarf king. I don't know if it was a lost adventurer or one of the mummies by a red dragon cave that breathed flies everywhere but the hammerman's neck, brain, upper and lower spine all rotted and he started vomiting everywhere which was fairly entertaining.
Eventually the dwarf king sent me to a dark fortress he's at war with to go kill a high priest, so I went to do that. Turns out that the fortress is populated by dwarves, I'm guessing because of overzealous goblin babysnatching.
Anyway, the priest got the axe and I freed about 10 prisoners and went home. On the way I was attacked by gargoyles (And there's a LOT of gargoyles in the dwarven kingdom) and I suddenly realised that freeing those prisoners might have been a mistake, because of the obsidian dwarf child and the 2 aspid dwarf children breathing fire and aspid stuff everywhere.
The aftermath wasn't as bad as I thought, but the two nord warriors became paralysed and suffocated. I'm not sure if that was because of aspid breath or the diseases they had picked up earlier. So I went and looted their stuff and started getting You are melting! messages. Turns out a stray fireball managed to set fire to my upper body fat. I managed to survive that burning away (bled a lot though) and now my upper body fat is gone.
In summary, I have to say I love this mod, even though I haven't even seen a fraction of what's in it yet.
