All he really had going for him was being a Great Tracker. Now he's attempting to cook the books, after spending a good year as my underwater excavation unit.
Underwater. Excavation. Unit.
Did you just invent a new way to breach aquifers?
Hell, yeah! There's science to be done!
As for the detection, nickname bug was never necessary part of the detection, just examining migrant's skills in therapist is enough to find them. But trial by zombie or water is good idea anyway.
He worked hard expanding my aquifer supplied well system. Added well #2 for the hospital with #1 functioning as the meeting area. Really he only punched the last bit and the 2-zlevels of Well 1 mostly filled 1 zlevel of well 2. However, he sat there for about a year, eventually becoming a great swimmer. Which was annoying since he needed to punch the drainage corridor on z-level 2, so well #2 could fill completely.
So I opened up z-level 2 of well #2's wall and mined out a down staircase in the hopes, he might swim over. By this point he was Great Swimmer or some such.
Nothing
Tried disabling labors, giving him an office and making him the bookkeeper and manager.
Nothing.
Got annoyed, and drained my well cisterns with DFhack, and opened up the constructed wall of well#2 on it's bottom zlevel.
Idiot sat there.
When the water started flowing back in, it pushed him away from where he'd been standing/swimming all this time, he'd try to return to the spot, eventually the water pushed him 2/3 of the way to well #2 cistern, and he just decided to run out and go cook the books.
I am wondering now, if I could release this desperately thirsty little sucker and have him dig into well#2 with some staircases, and excavate well #3 just to see if he will dig in and keep going. I'll cram everyone into the dining hall and release him at some point.
Actual direct breaching of an aquifer, I could use him for that easily. However, I wouldn't want to use a vamp to try to punch straight through an aquifer to get to real rock. I haven't seen one vampire until after the first two hard-coded waves arrive. I'd hate waiting on the surface all that time, to hopefully get lucky.
