@Meph:
How about including
Stupid Dwarf Stunts too?
When you run the syndrom there's 1% chance of random death, or 1% chance of a stunt, with 50% fatality/crippling rate. I saw Putnam helped you with a skill script, that could be used to give a bonus after a successful stunt.
Urist McHauler took a wheelbarrow ride to the bottom of the stairwell.
-Urist McHauler broke his neck.
-Urist McHauler gained +1 Agility.
Urist McKid tried the exploding cat-trick.
-the flying cat torso hits Urist McKid in the head, breaking the skull and jamming the brain.
-Urist McKid gained +1 skill in
Alchemy Chemistry.
I don't think it's possible, but it would be an added bonus if the stunt they execute is somehow connected to their personality/skill, so not completly random. Or: idle dwarves have a higher chance of executing a stunt then busy dwarves.
